PG7
The PG7 Piston Seal is a compact, bi-directional seal designed for medium to heavy-duty hydraulic cylinders. The two component design consists of a Hytrel® HY55 seal ring and a 70 shore A NBR square energizer. The high strength seal ring material provides excellent seal extrusion resistance.
PG7 series piston seals are designed to retrofit standard North American housing standard (NFPA T3.19.18), which is commonly referenced as a rectangular piston seal.
