DESCRIPTION
The PS2000 piston seal is a double-acting piston seal capable of passing over ports. The reinforced, heat stabilized, thermoplastic sealing face expands and contracts to fill the gap between the piston and the cylinder wall and has a step-cut joint for easy installation.
The PS2000 piston seal will tolerate a considerable extrusion gap, reducing the possibility of piston to bore contact. It also offers excellent static load holding capability, and can easily pass over ports.
The square section nitrile energizer responds quickly to pressure changes, providing excellent sealing characteristics under all pressure conditions.
This seal is interchangeable with the PS914 style
