Elastomer Seal Comparison

Buna-N Viton
Compound N674-70 V747-75
Color Black Black
Bakeout 80°C 150°C
Benefits Seals easier, lower cost High temperature, lasts longer

Viton® is recommended where temperatures, chemical resistance or long installed life make it beneficial. Use Buna-N where temperatures are moderate, and installed useful life is consistent with this material. The centering ring is available in stainless steel or aluminum. Use stainless steel where chemical resistance is needed. Flanges and seals are designed to be tightened to metal to metal contact.
