What to make a gasket for a carburetor from

Numerous gaskets and washers can be rubber or cardboard; paronite is also used for this purpose, which is used in places where the operating temperature of the unit does not allow the operation of rubber or paper parts. In addition, to ensure sealing of components operating in particularly harsh conditions, a textolite gasket is used.

A device that uses all types of the listed materials is the carburetor, and despite the fact that this part is no longer used to prepare the working mixture in modern cars, a garage mechanic may need information on how to change or make a gasket for this part.

Blog named after sancta → Making gaskets (my experience)

Today I want to talk about how I make pads.

On the Internet I found a description of what people make gaskets from. I used to make them from paronite. But I don't like the material itself. The oil makes paronitis soft like snot. The connections need to be constantly pulled, it gets wet and looks extremely sloppy.

Paper is the best choice. And because I work in the printing industry - I could have chosen the paper for the gaskets more consciously. I’ll say right away that I don’t like coated paper (from magazine covers, as advised in

Internet), although I had a huge choice of this one. I think its main disadvantage is that it practically consists of only chalk (and now there is just a wave of low-quality paper from China). Whatever one may say, chalk is an abrasive. Although very weak. Nobody wants to have abrasive in their engine. A more or less suitable paper is chrome ersatz (as on doctors’ magazines, medical records). But still, there is also chalk on this paper.

I had a criterion - no chalk. And it seems that such paper simply does not exist for printing! But it exists in a different form. So - I found her. Write down the name - calibrated cardboard (I had PAVAN) 0.5 mm, color - gray. Refers to under-deck materials (placed under offset rubber). You can find them in companies selling printing supplies. And also in printing houses with offset machines. This cardboard is replaced by printers and simply disposed of after some time. If you have friends, go and ask.

The main advantage of this cardboard is that it is really tough. There is no chalk in it. And it is very accurate (the difference in thickness is no more than 0.01mm).

My method is not fast, but it is as accurate as possible for home use.

We take the sealant and apply a thin layer to the surface. I just take the sealant on my finger and tap it lightly (I apply thermal paste to the processor in much the same way). Next, I place the sheet on a flat surface and press the lid against the paper with something heavy.

In my case, I pulled the lid through the hole in the center using a pin.

Then I wait about a day (that’s why this method is not fast). I roughly cut around the perimeter with a margin of a couple of centimeters with scissors.

The cardboard has already been properly adhered to the surface using sealant.

We take a stationery knife with this grip and cut off the outer contour.

Next, to find the inner contour, press the contour with your fingers. It was not visible in the photo, but after this the internal contour begins to be clearly visible. We cut the inner contour in the same way

I carefully drilled the holes with a punch I made (it’s still good to have a lathe on hand!)

And the result is quite decent. Next, purging, rinsing with alcohol.

Applying sealant to the mating part (try to use the minimum amount of sealant).

And one more “trick” - pulling with a screwdriver with a torque limit. Gradually adding torque we tighten all the bolts. Leave it for a couple of hours and tighten it with a key (without fanaticism).

This is not the first renovation using this technology. I have used such gaskets several times already and there are no problems with them. They don't get wet or sweat. They hold up great. Knowing this technology, I am not afraid to open the engine even for inspection. Because I know that I can make this gasket myself for free.

I hope this information helps someone and good luck to everyone on the roads!

Paronite gaskets for water: how to choose a manufacturer, description of models

Paronite gaskets are products made from asbestos, rubber, and special additives. With their help, they create tight connections in various pipelines. These products are used in water supply systems of apartments, houses, and enterprises. Ensures the strength of connections.

Features of paronite gaskets

Paronite is a sheet material containing 2/3 asbestos fibers, synthetic rubber, sulfur and special fillers.

The strength of the product is enhanced by reinforcement with metal mesh. Parts for sealing any joints are made from this material. Under a certain pressure, paronite turns into a viscous mass. In this form, it fills unevenness and ensures tightness.

Modern equipment produces parts of non-standard shapes. For this purpose, an algorithm for releasing elements is being developed. Gaskets are made using industrial cutting.

The material is very plastic. Parts of the desired shape are cut out from a paronite sheet of a certain thickness.

Paronite gaskets are used in a wide variety of areas:

metallurgical industry;
oil and gas industry;
Food Industry;
communal and economic area.

The parts are mainly used for sealing water supply pipes, pumps, and heating systems. In pipelines carrying gaseous and liquid media. They serve as adapters at the joints of flat pipes.

The products have the following advantages:

high temperature resistance, used for cars, engines;
withstand high pressure;
retain properties at different temperatures.

The disadvantages include:

possible manufacturing defects;
violation of operating requirements.

They produce several product options:

General purpose paronite gaskets, PONB.
Oil and petrol resistant parts, PMB.
Acid-resistant PCs.
Reinforced, PA.

At a temperature of 200 degrees and a pressure of 40 bar, non-reinforced gaskets are used. Reinforced products can withstand higher pressure and temperature.

Popular models

Products marked PON

They produce more than 10 brands of paronite with different characteristics and areas of application. Products marked PON are used in a neutral environment. PMB is used in engine rooms, diesel rooms, and when working with petroleum products.

PON, PON-A, B, B are used for tightness of connections in a neutral environment. Withstands high temperatures. rubber and asbestos ensures the elasticity of parts. They are easy to cut and stamp.

At a pressure of 32 MPa, the material becomes fluid and fills all gaps and gaps. Seals any fixed joints of pipelines, shut-off valves, and mechanisms.

The surface of the part is treated with graphite to prevent sticking to the metal.

PON-A: the brand is used in the environment of saline solutions, steam, superheated water.

PON-B is used for tightness in saturated vapors. In an environment of neutral and dry inert gases, complex petroleum products.

PON gaskets are used to seal joints of communications and equipment transporting superheated liquid, water and steam under pressure. At electrical and thermal stations, boiler houses. In metallurgy and the chemical industry, heating systems, household appliances.

PMB, PMB-1 are resistant to any type of aggressive environment and can withstand high temperatures. Used for compressors, internal combustion engines, petroleum products, oxygen, nitrogen.

The PMB brand is used for sealing joints in various devices, pumps, compressors, and pipelines. In an environment of oils, molten wax, liquefied and gaseous substances. In the production of electricity. In metallurgy, coke and food industries.

PC is resistant to aggressive environments, acids and alkalis. It is used in a chemical environment and can withstand a maximum pressure of 10 MPa and a temperature of 250 degrees.

Criterias of choice

Paronite gaskets comply with GOST requirements. When choosing products, appearance is taken into account. They must be smooth, without swelling, flaws, folds, or breaks. During shaping, parts should not crumble or break. Slight fluffiness is allowed; the material may not be painted.

Sheet thickness is an important criterion when choosing. If it is smaller, it will not provide high-quality sealing and will not fill the space. A product with greater thickness cannot withstand strong pressure, the tightness and protection are compromised.

Paronite parts have standard length, width and weight.

Installation and fastening

Flange joint sealing diagram

Before installation, the new gasket is treated with oil and graphite. This prevents sticking to the flange surface. The edges of the product should touch the bolts, the internal diameter coincides with the diameter of the pipe. The outer size corresponds to the parameters of the bolts. Installation procedure:

The main and counter flanges are selected of the same type and aligned.
The fasteners must not exceed the required load.
Additional tightening of the bolts is performed after exposure to elevated temperatures.
There should be no corrosion on the fasteners, this weakens the ability to withstand the load.
The gasket grade matches the connection specification.
Washers and nuts are selected from the same material.
If necessary, apply lubricant to the threads.
Parts use an acceptable thickness.

Paronite gaskets strictly comply with GOST standards. Uniform thickness guarantees reliability and strength of connections.

Types of breakdowns

Paronite is a durable and high-quality material; parts wear out quite rarely. The cause of failure is loss of tightness associated with mechanical or chemical influences. A breakdown or burnout of the gasket occurs.

Causes of breakdowns:

incorrect installation or replacement of an element;
bolts are too tight;
incorrect selection of gasket;
overheat;
presence of malfunctions.

If problems arise, replace the gasket with a new one.

Paronite is a unique material used in the form of gaskets for reliable sealing of joints. It has high performance properties. Raw materials are available and durable. Among the advantages is the low cost of the material.

Necessary materials

Here's what you can use to make a carburetor gasket:

Paronitis.
Gasoline resistant rubber.
Metal asbestos.
Cardboard.

Here is a basic list of materials suitable for making gaskets.

Unfortunately, these materials are not always at hand for the car enthusiast, but cardboard is available to everyone and in large quantities. It should be dense and have a thickness of about 0.8-1 mm. This is the most common material among car enthusiasts who have decided to acquire the skills of an auto mechanic. And it’s not always possible to complete the required work the first time, the work is quite delicate, you can ruin more than one workpiece, wasting expensive and scarce materials in vain, but cardboard is always at hand and the quality of the gaskets made from it is very good.

The structure of a lawn mower and common malfunctions

The easiest way is to have your lawn mower repaired by allocating a certain amount of money from the family budget; prompt and high-quality repairs with your own hands are no less simple and convenient if you want to understand the design of the lawn mower and fix all the problems.

Knowing exactly the internal structure and operating principle of the trimmer, you can independently carry out repairs to the structure or replace individual components that have become unusable, using the repair instructions.

All these problems can lead to the device losing its functionality; before ordering the necessary spare parts for the mowing machine, a visual inspection and diagnostics of the device should be carried out.

Individual spare parts and assemblies of the device require special attention; to check them, you do not have to contact a professional technician; a set of diagnostic measures will help you to identify the consequences of loss of performance with your own hands.

Who can tell me what to cut out the gasket for the fluid coupling pan from, cardboard drips, silicone too.

Continue topic

Good old paronitis. Well, you can follow it up with sealant, just to be sure.

A gasket former will help you. if it doesn't work it will only hurt you

The bolts can spin and leak through them too.

Previously, they cut it out of the camera... onto the engine sump.

Rave! The camera is not petrol and oil resistant

enough to get there. I give you my teeth.

check the catalogs to see if there are any new ones in the wild, check the pan for distortion and integrity, and place it on sealant. All…

I have porn, I need to look at the thickness (I don’t remember). (Added after 1 minute)

Buy a good sealant, no gaskets needed!

It is normal to straighten the mating plane, especially where the bolts are pressed, otherwise no gasket or sealant will really help. Any flat surface will do, place a pallet on it and look from the side where there is clearance.

Suzuki Swift, 1.3cc, 2005.

It's clear. I have a new one for the Terrano/Mistral/Bongo automatic.

Gasket sealant “Done Deal” (black). We don’t have it in Smirnykh. Only in Yuzhny (in almost every auto shop). I’ve been using it for several years now. And those that sell here for 150 rubles are huge. In the Concept store I saw special Japanese original sealants - 1700 rubles per tube. It all depends on your desires, capabilities and love for your car.

Stupid for a good sealant.

The sealant is very good, gray specifically for the pallet, heat-resistant. The spread on top of the old gasket holds perfectly

Made from paronite + heat-resistant sealant. Or buy a new one.

can be made from high temperature sealant

you need to buy leaf paronite and cut it out.

Thank you everyone for the advice, we made the car, we bought a good sealant, they also suggested it, it’s called Autosila, we did everything according to the instructions, it holds up perfectly, my soul is glad that such things exist, and thank you again that there is the Internet and responsive people, emotions are overwhelming, ,,!

Good evening, dear forum users, please tell me, otherwise I’ve already lost my mind where to go, what to look at. So, when you smoothly accelerate from 0 to 30 approximately, the car experiences a certain vibration, as if you were driving on an uneven road, it’s so smooth, it feels like the rear wobbles. As a result, I changed the tires, wheels, cardan with suspension together, gearbox, rear drive, but the vibration remained as it was. The car is Mark X, 4 wd

Stages of work

First, remove the carburetor. We disassemble it and remove the old gasket. During all work, extreme care must be taken to avoid harming the parts inside the carburetor and to prevent the ingress of dust and various debris. Contact surfaces must be thoroughly cleaned. To cut out a new gasket, it is not recommended to use the old gasket as a template. There will be inaccuracies. Now let's analyze alternative materials.

Cardboard gasket

To cut the gasket exactly along the contour, the desired place should be coated with a thin layer, for example, grease, ink, etc. Then we apply a cardboard sheet to the carburetor so that not the slightest displacement of both parts occurs. Now it's done, all that's left to do is cut it out. The most convenient way to cut out a part is with nail scissors; finding them is also not a problem. You can punch the required holes using a specially selected tube, the edges of which are sharpened so as not to tear the part being manufactured. Place the workpiece on any wooden object with a flat surface, place the tube in the right place and hit it with a hammer as sharply as possible. It doesn’t hurt to lubricate the finished gasket with sealant, but only a little, otherwise the excess sealant will squeeze out into the float chamber after assembly.

It is necessary to take into account the thickness of the new part and if it is thicker than the original, you should adjust the position of the float and reconfigure the carburetor at idle. There is nothing complicated about replacing the gasket yourself, and there is no financial investment either. Special attention was paid to the cardboard, now briefly from what you can cut out the gasket for the carburetor.

Paronite gasket

Paronite is a good option, but gasoline causes it to peel off, crumble inside and clog the carburetor channels. Of course, there is also petrol-resistant paronite, but it is not always and not available everywhere.

Material for HIGH TEMPERATURE gasket

I have such a tricky joint in my exhaust system - two intertwining pipes are welded into a flange, which is tightened to the second part of the exhaust with 8 bolts. (what is between the pants and the resonator)

There was never a gasket there. I tried many times to find a similar one, but always missed.

The sound, of course, is cool - so bassy and soft. But I would like to get rid of it too.

THEREFORE

— I’m looking for a material from which I can cut something like a gasket for the exhaust system. Can you suggest such material? In the original, these gaskets are metallized on both sides - it seems that the metal is compressed during installation and the connection is tighter. By the way, the exhaust manifold gaskets are made from the same material..

In short, I signed, damn it... Is there an alternative, or not?

Breakdown of the starter and gearbox

The gearbox transmits torque from the motor shaft to the cutting tool; during operation, its gears must be absolutely clean and always lubricated with a special lubricant.

Carrying out a technical inspection on your own once a season will eliminate the need to repair the gearbox or replace it, with the purchase of an expensive new unit.

A starter is necessary to bring the trimmer into working condition; its diagnosis consists of checking the tension of the cord engaged with the teeth of the starter coil, which are often destroyed during a sudden start.

A non-working starter in a lawn mower cannot be repaired; it must be replaced with a working unit as part of a mandatory technical inspection or a set of repair measures.

The cutting elements require special attention and care; they must always be cleaned of dirt and mown grass after use. Regular inspection and thorough preparation of the device for operation will help you avoid expensive and time-consuming repairs, and always be confident in the functionality of the lawn mower.

Re: Material for HIGH TEMPERATURE gasket

Is there an alternative or not? Yes - Option 1 Buy the original gasket and don’t fool yourself. The price is a little more than 60 gr. Option 2. Order a gasket with a metal edging from craftsmen. This is real in Kharkov. Price about 30 gr. Option 3. Buy a piece of paronite on the market and cut out holes for the exhaust and studs. Price is negotiable (with the seller of paronite). Option 4. (Sucks, but sometimes it helped) Spread the joints with high-temperature sealant and wait until it hardens. Afterwards the system is assembled.

In addition, to ensure sealing of components operating in particularly harsh conditions, a textolite gasket is used.

Re: Material for HIGH TEMPERATURE gasket

buddy, there is a gray sealant specifically for mufflers (temperature sealant, and it smells kind of like formic acid, I don’t remember what it’s called, but sellers of mufflers generally always have it), you take your joint apart, lubricate it generously and put it back together, depending on the temperature - it becomes like a gasket, I have it smeared like this between the 2nd and 3rd jar because they don’t make gaskets there, they just tighten it with a ring, and also between the flame arrester and the second jar

Re: Material for HIGH TEMPERATURE gasket

pvdenis
, no, let me talk about sealants for the exhaust system! It's up to 600C - look at it on yours! And the putty, it seems to me, will crumble, especially on such a connection. After all, in the pits. when the pipe wobbles, the load at the place of this twist changes! There should be something more or less elastic there.. But the sealant is a good try, I’ll try it..

Regarding the fastening, on the Golf 2 the exhaust manifold and the pants are connected by a hinge clamped by two strong brackets. If you snap these staples, the pants “fall out” down. And if they fall out along with the resonator, it’s not a big problem
