As the coaxial sealing ring for piston specially, piston seal has outstanding use effect in compressor, servo valve and engineering machinery cylinder. 

Piston seal is bilaterally sealed and matched with a rubber O ring that provides pretightening force.

Advantages:

· Good anti-extrudability

· Avoid squeezing

· Superior friction resistance performance; small friction force

Application parameters:

Pressure: Smaller than 80 MPa

Temperature: -54℃-200 ℃, subject to the material of O ring

Speed: Below 15 M/S

Media: Subject to the material of O ring

Service life:Long service life due to low friction coefficient and high wearing resistance of PTFE materials. 

Scope of application:

Hydraulic cylinder and hydraulic valve
