PP Cushion Seal

PP Cushion Seals are used in pneumatic cylinders to absorb end-stroke impact, reducing shock loads, noise, and mechanical stress on cylinder components. Installed in piston or rod grooves, the seal compresses progressively at the end of stroke, allowing controlled deceleration and smoother operation.

Manufactured from NBR (Nitrile Rubber), the PP Cushion Seal provides good elasticity, wear resistance, and compatibility with air and lubricated pneumatic systems. The profile is designed to deliver reliable cushioning performance while maintaining consistent behavior over repeated cycles.

These seals are commonly applied in pneumatic actuators, automation systems, material handling equipment, and industrial air cylinders, where controlled motion and component protection are critical.
