Profile KB08D seal is a compact double acting / bi-directional composite piston seal which consists of a Hard PU sealing element and elastomer O-Ring energiser.

The O-Ring energises the sealing element and provides an effective leak free barrier around the inside diameter of the seal groove under static conditions and the hard PU sealing element provides a highly abrasion resistant positive seal against the cylinder bore counter face.

The KB08 can be used in conjunction with our KB08B profile to provide a complete leak free sealing configuration or where sealing redundancy is required.
