Value Collection 0M284B2.4 Buna-n Round Cord Stock

Product Description

The VALUE COLLECTION 0M284B2.4 is a Buna-N (nitrile rubber) round cord stock supplied in a 100-foot standard coil. Buna-N is a synthetic elastomer widely used in sealing applications where resistance to petroleum-based fluids, oils, and fuels is required. This cord stock serves as raw material for field-fabricated O-rings, rope seals, and custom gaskets cut to length on the job. HVAC, plumbing, and industrial service technicians keep coil stock on hand to produce custom-length seals when pre-formed parts are not available or when a non-standard groove dimension is encountered.

This cord stock is suited for sealing applications in residential and commercial HVAC equipment, plumbing systems, compressors, and fluid-handling assemblies where nitrile rubber is compatible with the working fluid or refrigerant. The 100-foot coil length provides sufficient material for multiple field repairs or shop fabrication runs. Installers working with oil-resistant sealing applications in equipment such as compressors, valve bodies, and pump housings will find this round-profile cord appropriate for groove-seated static seal configurations.

Key Features

• Buna-N (nitrile rubber) material provides strong resistance to petroleum-based oils and fuels
• Round cross-section profile suits standard O-ring-style groove geometries
• 100-foot coil allows field cutting to any required seal length
• Flexible elastomer construction enables use across a range of operating temperatures typical in HVAC and plumbing environments

Compatibility

Designed for use as a field-fabricated sealing cord in applications requiring nitrile rubber elastomer compatibility, such as oil, fuel, and many hydraulic fluids. Confirm fluid and temperature compatibility before installation.

Installation Notes

Cut to required length using a sharp blade on a clean, flat surface to ensure a square end for a proper butt joint. Isolate and de-energize or depressurize the system before replacing any seals. Buna-N cord is not compatible with glycol-based fluids, polar solvents, or ozone-heavy environments — verify suitability for the specific fluid and operating condition. Installation of custom-fabricated seals in pressure-bearing systems should be performed by a qualified technician following applicable codes and equipment manufacturer guidelines.
