PTFE gaskets are the ideal choice for highly corrosive environments which do not include beer or wine. PTFE is a versatile material, similar to Teflon, with a broad range of resistivity to chemicals and temperatures (-100°F - 450°F), and virtually no extractables. PTFE is a plastic, however, and is subject to creep and cold flow. PTFE gaskets should be used almost exclusively with high pressure clamps and are not recommended where large temperature variations occur. Gaskets and Seals are non-returnable.
What type of material should I use?
While we are prohibited from recommending a gasket type, we do offer a Chemical Resistance Chart (new window) that matches the resistance level of gasket materials to the different chemicals / food products you may be using. We may suggest using an A- or B-rated gasket for your particular application.
