MECHANICAL SEAL
PSP/CPV profile is a squeeze-type, bi-directional piston seal for use in light to medium-duty hydraulic applications. The PSP's seal geometry provides a fluid reservoir between the two sealing lips, which holds system fluid, resulting in lower breakaway and running friction. It is designed to retrofit no-back-up O-Ring-type grooves.
Made from Shore 65 D PTFE, these devices are designed to absorb shock loads and are used to prevent extrusion of loaded lip seals under high pressure. Contact us for other compounds and sizes. Temperature: -328°F to 500°F. (-200°C to 260°C)
