piston combination seal

Performance and Application

 It consists of two guide rings which play a role of supporting and guiding, two retainer rings which play a role of protecting the seal and guiding, one elastic rubber ring and one sealing ring. Elastic rubber ring provides enough pre-tightening force and compensates the wear of sealing ring to ensure good high/low voltage sealing performance. It is applicable to hydraulic cylinder piston seal and suitable for high-pressure overloaded bidirectional (double-actomg) seal especially.

Rotating Speed: ≤1.5m/s

Working Temperature: -40°C~+200°C (Depending on the material of rubber ring)
