DESCRIPTION
The MPSU profile double acting piston seal is a compact low friction seal for light to medium duty hydraulic cylinders.
The MPSU comprises a tough, wear resistant thermoplastic elastomer face, which is pre-loaded by a nitrile O-ring. The houlsing width allows a narrow width piston to be used, but it is recommended that an adequate bearing is mounted on one or both sides of the seal.
These seals are interchangeable with style MPS seals of the same dimensions.
