Copper Nitrate Resistance PTFE Seal

Copper nitrate resistance PTFE Seal

Spring energized PTFE seals can be used in applications that require ultra-low 

friction, chemical compatibility and extreme temperatures.Nowadays, spring energy storage seals have  

been widely used in aerospace, automotive and energy fields. Specific application cases include jet 

engines, helicopter rotors, oil field equipment, and fuel pumps.

The spring energized seal is a high-performance seal with a special spring assembled in U-shaped PTFE. 

With proper spring force and system fluid pressure, the sealing working lip is pushed out and gently 

pressed against the sealed surface to produce a very excellent sealing effect. The sealing working lip 

has the best short and thick characteristics, which reduces friction and extends life.

Kaflon is equipped with European imported seal cutting equipment and multiple sets of spring 

tension testers, Seals low temperature test equipment, and Laser welding machine.In detailed:
