EPDM Tri-Clamp Gaskets EPDM Tri-Clamp gaskets are the preferred choice of material for brewing and similar alcohol based applications. EPDM 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: EPDM is not recommended for use with hydrocarbons Key Features: Low temperature range Low costs Better compressibility and springiness Excellent resistance to alcohols Good tear resistance Good abrasion resistance FDA CFR 177.2600 - Rubber and Rubber-Like Material for Repeated Use/Contact with Food.
