Item Information

The profile OK piston sealing set is primarily designed for heavy-duty hydraulic applications and is preferably used in double-acting cylinders. It is extremely robust and withstands even extreme pressure peaks.
The sealing set consists of a plastic slide ring and an elastomer energizer.

• Extreme wear resistance.
• Easy installation on single-part piston without assembly aids due to the split design of the sealing ring.
• Assembly on one-part piston is possible.
• Insensitive to extreme pressure peaks.
• Extremely high extrusion resistance.
• High extrusion resistance in case of high pressures and large gaps due to the special compound properties of the seal ring.
• Dimensions according to ISO ­7425-1.
• Short axial assembly length.
• Installation in closed and undercut housings.
• Further dimensions of machined series with short lead times available.

Range of application:
Heavy-duty hydraulic applications.
