PTFE Teflon Gaskets

PTFE Teflon Gaskets
PTFE (Polytetrafluoroethylene) is an inert material and so has excellent chemical resistance. PTFE gaskets are mainly used in the presence of aggressive chemicals: such as acids, bases, and solvents.

PTFE ENVELOPE GASKETS

PTFE ENVELOP Gaskets
Metals are only used in the annealed condition and limit the hardness of the metal in line with international standards as shown.

Fillers

INSEAL supplies custom PTFE envelopes, or envelope pipe gaskets, that have numerous benefits. PTFE envelope pipe gaskets are produced and fabricated with a PTFE protective covering envelope; the advantages of this configuration include excellent resilience, outstanding mechanical strength, and superb bolt retention – these attributes are attained due to the chemical resistance characteristics of PTFE compressed sheet. PTFE envelope pipe gaskets are available in a range of thicknesses, with various fillers including EPDM, Viton ®, white neoprene, compressed sheet, silicone, butyl, and numerous others; PTFE envelope gaskets can be custom fabricated for a wide range of pipe sizes. Industries served include the petrochemical and chemical sectors, for applications such as glass-coated steel flanges

INSEAL has the experienced staff and equipment available to not only custom manufacture and fabricate PTFE gaskets, but can also produce PTFE custom parts, including heat exchanger gaskets, pads, and other custom components for a variety of industrial uses. In other words, INSEAL can custom fabricate – flat cut, die cut or water jet cut – practically any custom part from PTFE to your specifications.
