TFG/TFP Bearing Gaskets Back-up rings
PTFE gaskets have great resistance to most mineral and organic chemicals such as acids, bases, and solvents, and can be used up to approximately 240°C. The PTFE gaskets are good for use with petrol & oils and excellent choice for use with acids and alkalis.

Description
Structural Design:
The gaskets of PTFE have good ozone resitance and good impermeability to gases.
The PTFE raw material for the gaskets has probably the best possible friction coefficient.
PTFE gaskets are generally used in the presence of aggressive chemicals.
The PTFE gasket can be designed as a bore liner to shield pipe gaskets from the chemical attack.
These are supplied to fit the bore size, and are known as PTFE envelopes.
Summary of Advantages:
- Has excellent chemical resistance
- Can maintain its shape and function even under extreme conditions
- Low friction coefficient
- High pressure creep resistance
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
