Value Collection 0284750 Buna-n Round Cord Stock 0.75 in

Product Description

The VALUE COLLECTION 0284750 is a Buna-N (nitrile rubber) round cord stock supplied in a 100-foot standard coil. Buna-N cord stock is a general-purpose elastomeric sealing material used to fabricate custom O-rings, gaskets, and compression seals. The cord measures 0.75 inches in diameter and is cut to length in the field using standard utility or razor tooling. Nitrile rubber provides solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making this cord appropriate for use across plumbing, HVAC, and fluid-handling applications where a molded O-ring is not available or not practical.

This cord stock is suited for maintenance and repair situations where a technician needs to fabricate a custom-length seal on the job. Typical applications include sealing flanged joints, stuffing box packing, groove-mounted compression seals, and inline fittings in oil or water service. The round cross-section seats readily into standard O-ring grooves. Plumbers, pipefitters, and HVAC mechanics commonly use round cord stock when replacing worn or damaged seals that do not have a readily available molded replacement.

Key Features

• Buna-N (nitrile rubber) material offers resistance to petroleum oils, fuels, and water
• 0.75 inch diameter round cross-section seats into standard O-ring grooves
• 100-foot coil length allows multiple cuts from a single unit
• Inch system of measurement for straightforward field sizing
• Flexible construction allows bending into custom seal diameters and shapes

Compatibility

Designed as a general-purpose field-fabrication sealing material for use in plumbing, HVAC, and fluid-handling systems requiring a 0.75 inch diameter nitrile rubber round cord seal.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC mechanic. Shut off and depressurize the system before removing any existing seal or fitting. Cut cord stock to the required length using a clean, straight blade cut to ensure a flush butt joint when the cord is formed into a ring. Bonding adhesive compatible with nitrile rubber may be used to close the joint; verify adhesive compatibility before use.
