Rubber gaskets can be used for:

•  Anti-vibration

•  supporting mounts

•  noise reduction

•  Sealing (the most common use)

You’ll most commonly find these types of gaskets between two pieces of pipe. Gaskets can also be used as a barrier between two objects, such as two metals or chemicals and are often used as protection from outside elements as well, such as in a camera lens, to combat moisture and dust.

While gaskets can be made from a variety of materials, one of the top choices is rubber. Rubber comes in a wide range of formulations and grades, each of which offers distinct characteristics that make it suitable for different applications:

•  Neoprene

•  Nitrile (Buna-N)

•  Ethylene Propylene Diene Monomer (EPDM)

•  Silicone Rubber

•  FKM

•  Styrene Butadiene Rubber (SBR)

•  Butyl Rubber

•  Natural Rubber

•  Polyurethane Rubber

•  Food Grade (FDA Approved) Rubber
