Rod Seal XSRS02C
Function:
Rod seals are designed to seal the pressurized hydraulic fluid against the atmosphere, preventing leakage and pollution of the environment.
Features:- Asymmetrical, single acting rod seal with anti extrusion ring, designed with interference on the OD which provides a good static fit in the groove.
- Primary seal in tandem arrangements of heavy duty applications.
- Thin and flexible static lip to enable pressure relief, built up between primary and secondary seal.
- Replacement for the primary O-Ring energised rod seals in tandem arrangements.
- Not recommended as single/main seal in sealing systems.
- Suitable for high pressure peaks at about 700 bar.
- Radial grooves on the sealing lip recommended to reduce any risk of „blow-by“.
- Useable for long stroke lengths.
