DESCRIPTION
The MPSB is a double-acting compact piston seal designed for medium duty hydraulic applications. The seal is comprised of a fabric-reinforced nitrile sealing ring and two L-shaped polyacetal guide bearings.
The MPSB seal ring is a nitrile base to provide optimum elasticity and low compression set. This base is encased in fabric-reinforced nitrile that provides high mechanical strength, optimum thermal stability and extrusion resistance.
The polyacetal guide rings provide high distortion and extrusion resistance.
The MPSB is designed for one-piece or two-piece pistons.
