Envelope gaskets

Envelope gaskets are perfect alternative for typical gaskets made of gasket sheets. It is possible to improve chemical resistance of gaskets by using PTFE envelope. PTFE adaptability provides tightness even with low bolt torque. Envelopes prevents the material from creep and extrusion. The filler can be gaskets sheets, rubber sheets or metal rings with graphite. Using graphite prevents thermal shocks and risk of micro-crackings or leakage.
