Value Collection RWH2000H90 Air Cylinder Nitrile Rod Wiper

Product Description

The VALUE COLLECTION RWH2000H90 is a nitrile rod wiper seal designed for use in pneumatic air cylinders. Rod wiper seals sit at the end cap of an air cylinder and scrape contaminants off the piston rod as it retracts, protecting internal seals and extending cylinder service life. This part measures 0.275 inches in height and is constructed from nitrile, a synthetic rubber compound well suited for contact with petroleum-based lubricants and hydraulic fluids. It is a standard replacement component installed by fluid power technicians, maintenance mechanics, and industrial service professionals.

This rod wiper seal is intended for pneumatic cylinder repair and maintenance applications where the original seal has worn, cracked, or allowed contamination ingress. Nitrile material performs reliably across a broad range of shop-air and light hydraulic service environments. Typical installation occurs during cylinder rebuild, end cap service, or scheduled preventive maintenance on production and automation equipment.

Key Features

• Nitrile construction resists petroleum-based lubricants and light hydraulic fluid exposure
• 0.275 inch installed height suits standard air cylinder end cap groove dimensions
• Serves as a rod wiper to exclude dirt, chips, and moisture from cylinder internals
• Lightweight at 0.0625 pounds, minimizing handling and installation difficulty
• Single-piece replacement unit packaged individually for single-cylinder rebuild use

Compatibility

Designed as an OEM-style replacement rod wiper seal for pneumatic air cylinders requiring a nitrile seal with a 0.275 inch height profile. Verify bore diameter, rod diameter, and groove dimensions against the cylinder end cap specification before installation.

Installation Notes

Installation is performed by fluid power technicians or qualified maintenance personnel. Depressurize and lock out the pneumatic circuit before disassembling the cylinder end cap. Inspect the rod surface for scoring or burrs prior to fitting the new wiper seal, as rod damage will accelerate seal wear. Lubricate the seal lightly with a compatible grease before seating it into the end cap groove to avoid tearing during assembly.
