Norgren 60335 Pneumatic Cylinder Piston Seal Nitrile

Product Description

The NORGREN 60335 is a nitrile (Buna-N) piston seal designed as a replacement component for pneumatic cylinder pistons. This seal maintains the pressure boundary between piston faces inside an air cylinder, preventing internal air bypass and ensuring consistent actuator force and stroke performance. At 0.09 inches in cross-section width and 2 inches in length, it is a compact, lightweight part weighing approximately 0.01 pounds. It is typically installed by pneumatic technicians and maintenance professionals servicing industrial or trade-grade air cylinder assemblies.

This piston seal is suited for use in pneumatic cylinder piston applications where a Buna-N elastomer material is specified. Buna-N nitrile provides resistance to petroleum-based lubricants and compressed air service, making it appropriate for standard industrial pneumatic circuits operating under moderate temperature and pressure conditions. It is a direct replacement-style seal intended for use during cylinder rebuild or preventive maintenance procedures.

Key Features

• Buna-N (nitrile) elastomer construction for petroleum lubricant and air service compatibility
• Compact cross-section width of 0.09 inches suits tight piston groove tolerances
• 2-inch length accommodates standard piston seal groove dimensions
• Lightweight at 0.01 pounds, minimizing added mass in actuator assemblies
• Single-piece package quantity supports individual cylinder service jobs

Compatibility

Designed as a replacement piston seal for pneumatic cylinder piston assemblies where a Buna-N nitrile seal material is required.

Installation Notes

Installation is performed by qualified pneumatic or mechanical technicians. Before servicing, depressurize and lock out the pneumatic system supplying the cylinder in accordance with applicable OSHA lockout/tagout procedures. Inspect the piston groove for wear or damage before seating the new seal, and use only clean, compatible lubricants approved for nitrile elastomers. Avoid overstretching the seal during installation to prevent compromised sealing performance.
