Rubber Gaskets
Rubber is the most cost-effective material to use where temperatures and pressures are low and the chemical environment is mild. Different elastomers offer different mechanical and chemical properties. Cloth inserted materials are better able to handle movement and high compression loads.

High temperature air or water (not oil or steam). Soft. Available in FDA grade. |
| Vinyl |
20 to 160 |
150 |
1/16 to 1/4 |
Water, oxidizing agents. Excellent weather/abrasion resistance. |
| Viton® |

Oil/Aromatic fuels, mineral, animal and vegetable oils, solvents and hydraulic fluid. |
Sponge: Neoprene, Nitrile, Silicone and Viton® are also available in sponge
form. Closed cell sponge is available for applications requiring high compressibility.
Open cell is available for cushioning applications where
sealing is not an issue. The basic physical and chemical properties are the
same as for the elastomers in the table above.
