Custom Seals

 

StandARD Seal Profiles

All seals are manufactured within our UK base which gives complete control and flexibility to support almost any demand. Our range of PTFE materials and compounds extends to more than 300 variations of Virgin unfilled materials through standard filled compounds all the way to speciality blended materials to suit particular applications.

High-performance seals can be designed and manufactured by AFT Fluorotec wherever durability and resistance to chemicals and temperature fluctuations are the norm. 

We can produce, solid, knife or saw-cut VICTREX® PEEK backup rings in virgin, glass or carbon filled PEEK.

WHY PTFE IS GREAT FOR SEALS

PTFE has many benefits making it ideal for sealing applications. Extremely high thermal stability, resistance to almost all chemicals, chemical inertness, Extremely low coefficient of friction (0.06), self lubricating properties, high melting point and the unique ability to resist thermal degradation.

PTFE is an ideal material for use in dynamic sealing applications, even when running dry as it does not suffer any stick/slip effect. This low friction characteristic also makes it the ideal choice for high speed dynamic applications as heat build up through friction is minimal. The addition of various fillers can alter some or all of these properties and can be adjusted to achieve desired physical properties to suit applications making our range of PTFE seals and materials extremely flexible

One of the main advantages of using PTFE for seals is the wide operating temperature range, –70 to +250 °C (–95 to +480 °F). 

From wipers and piston seals through to rod and rotary, our experience and expertise are second to none.
