Teflon is incredibly inert and resilient, making it a great choice for aggressive, caustic, temperature-extreme applications. It isn't very springy, though, so gaskets made completely of Teflon can be difficult to seal. Teflon envelope gaskets solve this problem by ensuring that the part coming into contact with your process liquids only touch Teflon. The center part is Viton rubber, which exhibits excellent elastomer memory at a wide range of temperatures. It allows your gasket to form a much stronger seal.

Our Teflon envelope gaskets are made in the USA in an ISO 9001 facility with genuine Dupont Teflon™.
