Gaskets

PTFE envelope gaskets

Envelope gaskets consist of an enclosure, commonly called an envelope, which can be made from the more common virgin PTFE and filled PTFE (silica, graphite or other). The thickness of the envelope is usually 0.5 mm; this makes the gasket particularly suitable for the chemical, pharmaceutical and food industries. The casing can be supplied in different shapes and set-ups (U-envelope, closed, Y-shaped, etc.). The insert inside the gasket can be made of aramid fibre, graphite, ceramic fibre fabric, elastomers, modified PTFE, corrugated AISI rings and, on request, grounding fins. Such gaskets can be produced in various forms: oval, circular and as per design.
