Envelope protect the gasket from chemical attack and insert provide the strength and resilience needed for demanding sealing operation. gasket offer excellent chemical
resistance under moderate condition of temp and pressure. PTFE is also extremely anti-adhesive. This non-stick effect means that no material will adhere to the surface of the PTFE . PTFE envelope gaskets are available in a broad range of standard sizes and
configurations, as well as custom sizes upon request.

PTFE-enveloped gaskets are particularly useful with aggressive chemicals in the
chemical industry, due to their high resistant strength.

PTFE envelope gaskets are ideal for use in equipment employing flanges made from alloy, standard steel, glass-lined,plastic, ceramic, conical-end glass pipe and more.
