The 714 type double-acting piston seal is a compact seal for medium to heavy-duty applications. In double-acting telescopic cylinders or phasing cylinders, the seal's reinforced, heat-stabilized, thermoplastic sealing face with step-cut joint is an ideal choice because it allows the seal to pass over ports without damage. The rugged, extrusion resistant design also performs extremely well in high-pressure off-highway and earth-moving applications where the seal face can tolerate the large extrusion gaps which are required to prevent piston-to-bore contact. The abrasion resistant glass-filled nylon (GFN) face seal material allows the seal to work well on super smooth inside diameter (SSID) as drawn tube. The precision moulded face has chamfers which coupled with a profiled NBR expander allows for easier cylinder assembly.
