Value Collection K401-500 Air Cylinder Wiper Seal

Product Description

The VALUE COLLECTION K401-500 is a replacement wiper seal designed for use with pneumatic air cylinders. Constructed from a nitrile and cotton composite, this seal provides effective contamination exclusion at the rod end of the cylinder, helping to keep dirt, debris, and moisture from entering the cylinder bore. At 5/8 inch in height, it fits standard wiper groove applications found across a range of industrial and trade pneumatic systems. Maintenance technicians and industrial service pros install this type of seal during cylinder rebuild or preventive maintenance intervals.

This wiper seal is suited for pneumatic cylinder service applications in light industrial, manufacturing, and mechanical trade environments. It is typically installed during cylinder teardown and rebuild procedures where the original wiper seal shows wear, cracking, or loss of flexibility. The nitrile construction offers resistance to oils and common hydraulic fluids, while the cotton reinforcement adds dimensional stability under cyclic loading.

Key Features

• Nitrile and cotton composite construction for oil resistance and dimensional stability
• 5/8 inch height fits standard wiper groove dimensions
• Functions as a rod wiper to exclude contaminants from the cylinder bore
• Sold individually, suitable for single-cylinder rebuild jobs
• Lightweight at 0.0625 pounds for easy handling and inventory stocking

Compatibility

Designed as an OEM-style replacement wiper seal for standard pneumatic air cylinders requiring a nitrile and cotton wiper at the rod end. Verify groove dimensions against the original seal before installation.

Installation Notes

Installation should be performed by a qualified mechanic or pneumatic systems technician. Depressurize and lockout the air supply completely before disassembling any cylinder. Inspect the rod and bore for scoring or damage prior to installing the new seal. Avoid using sharp tools near the seal lip during installation to prevent nicking the sealing edge.
