Advantages of Piston T-Seals:
1. Easy installation
2. Extend service life and reduce overall maintenance work
3. With low leakage characteristics
4. Performs well under extreme pressure and temperature
5. Rated pressure over 40,000 psi.
Ordinary T-rings are more suitable for light-duty rotary seals. When compressive deformation, the section is fully supported and can adapt to high pressure without extrusion, while there is still a large area of contact with the groove to maintain stability.
Piston T-seals have a small friction contact area and the friction is comparable to O-rings. The retainer used with the rubber T-ring is best wound by spiral and can expand and contract with the deformation of the T-ring when the pressure changes.
