Rubber Gasket Materials


Gaskets are mechanical seals that prevent leaks between separate substrate sections.They are occasionally made of metal because they must be durable enough to withstand extreme pressures and wear.However,many gaskets,such as o-rings,can be made out of synthetic rubbers or silicone.These thick rubbers are robust enough to handle the kinds of pressure and conditions associated with gasket applications.

Gaskets come in many different shapes and sizes.

Types of Rubbers Used in Gaskets

Many types of rubbers are used to manufacture rubber gaskets,primarily due to the multitude of different environments faced by different applications.Some rubbers need to withstand both extreme cold as well as extreme heat,while others must withstand chemicals that may act as corrosives and could result in deterioration to many types of rubber.This makes heat and cold resistance,weatherability,and a lack of absorption a premium for gasket rubber,but toughness,flexibility,and friction properties should not be discounted.

The following list of materials is not intended to be comprehensive,but rather to represent some of the more common types of rubber used in rubber gasket production.

Nitrile rubber,or Buna-N,is a general purpose rubber with a good temperature range(-65 to 300 degrees F).It has good wear resistance and will not easily crack.

Ethylene Propylene(EPR)works well with hydraulic fluids that are corrosive and dangerous when exposed to human skin.Because of its high resistance to corrosive fluids,it is generally well-suited to applications that experience some amount of contact with other types of liquids.

Fluorocarbon often sold under the trade name Viton,is another all-purpose rubber that has a higher temperature range than nitrile rubber.It can be used in many diverse applications such as oils,fluids,and gases,as well as certain types of acids.

Neoprene has a low temperature rang
