Standard material:

sealing ring: filled with modified thermoplastic material, expansion ring: NBR


-Small shape
-Impact load resistance
-Even after the pressure is maintained for a long time, the friction between starting and moving is very low
-As the hydraulic cylinder seal ring is an open structure, it is easy to install on the integral piston without auxiliary tools
-High wear resistance
-Due to the special material performance of the hydraulic cylinder seal ring, it has strong extrusion resistance under high pressure and large clearance
-Suitable for grooves according to ISO 7425-1
