Hydraulic Sealing PTFE Seal

Hydraulic sealing PTFE seal 

The PTFE backup ring is used with low-pressure sealing rings such as O-rings, star-shaped sealing rings 

and U-shaped sealing rings. However, the most typical O-ring in the retaining ring, its role is to increase 

the gap between metal and metal moving parts. It can significantly improve and improve the sealing 

pressure bearing capacity and service life of this type of sealing ring, and it has been widely used in 

hydraulic sealing systems.

Features of PTFE backup ring:

(1) Low friction;

(2) No water absorption;

(3) High working accuracy;

(4) Wide temperature range;

(5) No hardening damage;

(6) No aging, etc. occurs at a temperature of 180°C;
