PTFE Milled Envelopes/ Bore Liners
PTFE envelopes (or bore liners) are available to fit 1.5 and 3.0mm thick gaskets, and to suit the range or bore sizes.
PTFE is a relatively expensive gasket material. However, a PTFE liner can be fitted to the bore of a standard gasket to increase its chemical resistance. Such a bore liner is known as a PTFE envelope.
PTFE (Polytetrafluoroethylene) is an inert material and so has excellent chemical resistance. It is mainly used in the presence of aggressive chemicals: such as acids, bases, and solvents.
