The 730 type double-acting piston seal in a four part assembly is designed for use in heavy-duty applications where position holding ability is important, such as longwall mining roof support applications using water-based fluids and large diameter crane cylinders using standard hydraulic oils. The seal is comprised of a tough, wear resistant thermoplastic polyester elastomer (TPE) face seal pre-loaded by a profiled nitrile rubber energiser. The design also contains a pair of rectangular polyacetal anti-extrusion rings. The standard TPE face material is suitable for both roller-burnished and honed tubing.
