DESCRIPTION
The MKPD profile is a compact seal for light to medium duty hydraulic cylinders. It is a double acting piston seal with single acting capabilities. This makes it an excellent choice for double acting applications where minimal dynamkc leakage is required.
The MKPD comprises a tough elastomeric face that is preloaded by a nitrile O-ring. The housing 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 can be substituted with MPSU seals of the same dimensions.
