BUNA-N Tri-Clamp Gaskets
EPDM Tri-Clamp gaskets are the preferred choice of material for brewing and similar alcohol based applications.
EPDMÂ Gaskets offer a low temperature rating and have better physical properties than Viton gaskets; the best part is that they cost less than Viton and provide the same chemical resistance to many alcohols
Note:Â EPDM is not recommended for use with hydrocarbons
Â
Key Features:
- Low temperature range
- Low costs
- Better compressibility and springiness
- Excellent resistance to alcohols
- Good tear resistance
- Good abrasion resistance
Â
Sizes Available:
- 1.5"
- 2"
- 3"
- 4"
- 6"
- 8" - easy on flanged
- 10" - easy on flanged
- 12" - easy on flanged
