Sakagami PSD-160 Pneumatic Piston Seal

The Sakagami PSD-160 is a double-acting pneumatic piston seal (piston packing) sized 160 × 140 × 7.6 mm, designed for use inside pneumatic cylinders to seal the piston as it moves. Made from nitrile (NBR) elastomer, it provides durable resistance to air and typical lubricants encountered in automated equipment. As part of Sakagami’s PSD packings line, the PSD-160 is intended for standard metric cylinder grooves and is used to minimize air leakage while delivering consistent actuation in automation systems. With its 160 mm bore, 140 mm rod reference, and 7.6 mm cross-section, the PSD-160 fits common piston-seal configurations found in medium-sized pneumatic cylinders, making it suitable for applications in manufacturing, packaging, and robotics where reliable piston sealing is critical. The double-acting configuration supports sealing performance in both stroke directions, contributing to smoother cylinder operation and longer seal life in demanding industrial environments.
