White PTFE / Black Viton® Envelope - ISO Sanitary Gasket

We have available the ISO #2852 and DIN #32676 hygienic standard flanged clamp gaskets in Pharmaceutical Class VI and FDA criteria in our specifically formulated compounds EPDM, Viton®, Silicone, and PTFE/Viton® Envelope. Our compounds are specifically formulated for Pharmaceutical and Biotech companies requiring the highest hygienic standards and chemical purity.

PTFE is the material of choice whenever low temperature flexibility or gasket memory is not required (not recommended where large temperature variations occur frequently, leakage can occur). PTFE has almost no extractables, has a low absorption rate and excellent resistance to process fluids. It can remain in service for longer periods of time in both water and steam. For continuous use, high pressure clamps are recommended to prevent leakage resulting from temperature variations.

This gasket meets all FDA Title 21 CFR 177.2600, USDA, 3A® and cGMP specifications.

PTFE gaskets are animal-derived ingredient free and meet USP Class IV, EP 3.1.9, and cytotoxicity specifications.

Temperature Range: -450°F to 550°F

Either a Certificate of Conformance or a Lot Traceable Certificate is available upon request at time of order.
