Product Description

PTFE Seals - PTFE O Rings - PTFE Gaskets - PTFE Shaft Seals - PTFE Guide Rings


We can offer a wide range of PTFE Sealing Products for applications requiring minimum friction, wide temperature range and maximum media resistance.

Material includes Virgin PTFE and mixes of carbon, bronze, graphite, glass and Mos2 filled PTFE compounds.

Suited for many applications, wide range includes: PTFE O-rings, Back-up Rings, Balls, Washers, Special Shapes, Lantern Rings, Valve Seats, Gaskets, Shaft Seals, Lip Seals, etc.


Benefits include:

Excellent Low friction

Extreme temperature properties

High wear resistance  

Excellent chemical resistance

Excellent dielectric properties


PTFE Seals are available in the following material specification:

Virgin PTFE

Used mainly for O Ring, Back-up Ring and machined parts used in special applications requiring chemical inertness and limited strength. Ideal for use in cryogenic applications.


Bronze filled PTFE

Typical application: Used in dynamic sealing applications where the bronze filler gives improved wear resistance, hardness and compressive strength. The electrical properties and chemical resistance are reduced. Molybdenum disulphide improves the self-lubrication.


Graphite filled PTFE

Typical application: Significant increased thermal conductivity, reduced level of creep. Self- lubricating, therefore suitable for high speed applications, without the need for exterior lubrication and applications which need to remove thermal energy and/or static electricity.


Glass filled PTFE

Typical application: Used where there is a need for improved wear and increased coefficient of friction. Ideal for high dynamic applications e.g. high rotation pumps.
