Pneumatic seal PS50A-M 56x63x10 NBR

The PS50A-M seal is designed for pneumatic applications, featuring a piston seal profile construction. The component is manufactured from high-grade nitrile rubber (NBR) with a hardness of 90 Shore A, ensuring adequate rigidity and dimensional stability under operating conditions. This element is fully compatible with the Z7 ring produced by Parker, allowing it to serve as a direct replacement in existing sealing assemblies.

The profile geometry is engineered to ensure proper contact with cylinder walls and effective separation of working media while maintaining a controlled friction coefficient. The NBR material exhibits good resistance to mineral oils, greases, and petroleum-based hydraulic fluids, contributing to stable system operation.
