Value Collection 0M284B8 Buna-n Round Cord Stock 100 Ft

Product Description

The VALUE COLLECTION 0M284B8 is a Buna-N (nitrile rubber) round cord stock supplied in a 100-foot standard coil. Buna-N cord stock is a flexible elastomeric sealing material used to fabricate custom O-rings, gaskets, and rope seals in the field or shop. The nitrile compound provides solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making it a practical choice for plumbing, HVAC, and general mechanical sealing applications. Technicians cut this round cord to the required length and splice or bond the ends to form a continuous seal sized to fit non-standard grooves or flanges.

This cord stock suits residential and light commercial applications where standard O-ring sizes are unavailable or a custom seal length is required. It is commonly used in pump housings, valve bodies, fluid fittings, and refrigeration service work where a field-fabricated seal is the most efficient solution. The round cross-section seats cleanly in standard groove profiles.

Key Features

• Buna-N (nitrile rubber) compound resists petroleum oils, fuels, and hydraulic fluids
• Round cross-section for use in standard O-ring and rope-seal groove profiles
• 100-foot coil length allows multiple custom-cut seals from a single stock length
• Flexible construction supports field fabrication and on-site splicing

Compatibility

Designed as a general-purpose field sealing material for use in plumbing, HVAC, and mechanical systems requiring custom-length nitrile round cord seals.

Installation Notes

A licensed plumber, HVAC technician, or qualified mechanic should isolate and depressurize the system before removing any existing seals or installing fabricated cord seals. Cut the cord to the required length using a sharp, clean blade to ensure a square end for proper splicing. Follow the equipment manufacturer's groove dimensions and splice adhesive recommendations when forming a closed-loop seal. Verify the finished seal seats fully in the groove before returning the system to service.
