Value Collection 0284125 Buna-n Round Cord 1/8 in 100 Ft

Product Description

The VALUE COLLECTION 0284125 is a Buna-N (nitrile rubber) round cord stock supplied in a 100-foot standard coil. This extruded elastomeric cord is used to fabricate custom O-rings, seals, gaskets, and other compression sealing components in the field or shop. The cord measures 0.125 inches in diameter with a tolerance of plus or minus 0.006 inches. Buna-N material offers solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making it a practical choice for plumbing, HVAC, and industrial fluid-handling applications. Installers cut the cord to length and join the ends to form custom-sized seals.

This cord stock is suited for residential and commercial maintenance applications where standard O-ring sizes are unavailable or where a custom seal diameter is required. Typical uses include sealing pipe fittings, valve stems, pump housings, and refrigeration service ports. The 100-foot coil length provides enough material for multiple jobs. The Inch measurement system and fractional 1/8-inch diameter make it straightforward to integrate with standard trade tooling and sizing charts.

Key Features

• Buna-N (nitrile) material resists petroleum-based oils, fuels, and hydraulic fluids
• Round cross-section cord at 0.125 inches diameter with tight 0.006-inch tolerance
• 100-foot coil provides ample stock for multiple custom seal fabrications
• Rated to -40 degrees F for use in cold-climate or refrigeration environments
• Inch-based sizing compatible with standard trade measurement practices

Compatibility

Designed as a general-purpose cord stock for fabricating custom O-rings and seals in plumbing, HVAC, refrigeration, and industrial fluid-handling systems where a 1/8-inch diameter Buna-N cord is specified.

Installation Notes

Cord stock seals are typically installed by plumbers, HVAC technicians, and industrial maintenance trades. Cut the cord to the required circumference using a sharp blade and a clean, square cut, then bond the ends with an appropriate nitrile-compatible adhesive to complete the seal. Depressurize and isolate any system before removing existing seals or installing new ones. Follow applicable codes and the equipment manufacturer's guidelines for seal material compatibility and compression fit.
