PSD Packings
Sakagami PSD pneumatic packings are compact double-acting piston seals that outperform O-rings in friction performance. Engineered to prevent twisting and rolling—common O-ring issues—PSD packings ensure smooth, reliable operation in pneumatic cylinders. Ideal for applications needing precision, compactness, and long-lasting performance.
