Value Collection NU6226-12 Air Cylinder Nitrile Seal

Product Description

The VALUE COLLECTION NU6226-12 is a nitrile replacement seal designed for use with pneumatic air cylinders. Nitrile (NBR) material provides reliable resistance to oils, greases, and hydraulic fluids commonly encountered in industrial and mechanical service environments. At 0.25 inches in height, this compact seal fits into standard air cylinder assemblies where maintaining a positive air seal is critical to consistent actuator performance. Installation is typically performed by maintenance technicians and industrial mechanics during scheduled cylinder rebuilds or unplanned seal failure repairs.

This seal is suited for pneumatic air cylinder maintenance across a range of industrial, manufacturing, and trade applications. It is commonly used during cylinder rebuild procedures where original seals have worn, cracked, or lost elasticity due to pressure cycling or chemical exposure. The nitrile construction makes it appropriate for environments where petroleum-based lubricants are present inside the cylinder bore.

Key Features

• Nitrile (NBR) material resists petroleum oils, greases, and common hydraulic fluids
• 0.25 inch height for installation in compact air cylinder seal grooves
• Lightweight at 0.0625 pounds, suitable for precision actuator assemblies
• Single-piece package for individual cylinder seal replacement

Compatibility

Designed as a replacement-style seal for pneumatic air cylinders that accept nitrile seal components of the corresponding height and profile. Verify cylinder bore diameter and groove dimensions against this seal before installation.

Installation Notes

Air cylinder seal replacement should be performed by qualified maintenance personnel familiar with pneumatic systems. Depressurize and isolate the air supply fully before disassembling any cylinder. Inspect the cylinder bore and piston rod for scoring or contamination before installing a new seal. Lubricate the seal lightly with a compatible, petroleum-based grease during installation to prevent tearing during assembly.
