Symmetrical piston/rod seals are designed to seal the pressurized hydraulic fluid against the atmosphere or between two pressurized spaces.


c:: Symmetrical, single acting piston/rod seal, no interference on the ID or OD.

c:: Wider groove and softer lips compared to PRS06. c:: Excellent static and dynamic sealing performance. c:: Excellent performance in low pressure conditions. c:: Useable for long stroke lengths.

c:: Negligible tendency to “stick-slip” effect above a speed of 0.15 m/s.


Reciprocating rods in hydraulic cylinders, plungers. Dynamic seals in hydraulic systems.

Max. pressure 400 bar, max. speed 10 m/s. Tandem arrangement possible.


Snap-in installation.

Attention: PTFE glide rings needs calibration after installation!
