Value Collection 0M284B5.7 Buna-n Round Cord Stock

Product Description

The VALUE COLLECTION 0M284B5.7 is a Buna-N (nitrile rubber) round cord stock supplied in a 100-foot standard coil. Buna-N is a synthetic elastomer well suited for sealing applications where resistance to petroleum-based oils, fuels, and hydraulic fluids is required. This cord stock is used to fabricate custom O-ring seals, gaskets, and packing by cutting to length and joining ends. It is a standard item for HVAC technicians, plumbers, and mechanical service professionals who need field-fabricated seals in sizes not covered by stock O-rings.

Round cord stock in Buna-N is a common consumable in residential and commercial HVAC and plumbing service. Typical applications include fabricating replacement O-ring seals for valves, flanges, compressor fittings, and pump housings. The 100-foot coil length provides enough material for multiple field repairs or shop fabrications from a single spool. It is stocked by shops that regularly service a variety of equipment where standard O-ring sizes may not be available.

Key Features

• Buna-N (nitrile rubber) material provides solid resistance to petroleum oils, hydraulic fluids, and fuels
• Round cross-section cord for fabricating custom O-rings and gasket seals
• 100-foot coil length supports multiple cut-to-length applications per spool
• Suitable for field and shop use by HVAC, plumbing, and mechanical service trades

Compatibility

Designed for general-purpose sealing fabrication in systems where Buna-N elastomer is chemically compatible with the fluid or gas being sealed, including petroleum oil, water, and common refrigerants where nitrile is rated for service.

Installation Notes

Cut cord to the required length using a clean, straight cut and join ends with an appropriate adhesive or splice tool to form a closed O-ring loop. Verify Buna-N chemical compatibility with the system fluid before installation, as nitrile is not recommended for use with certain synthetic lubricants or aromatic solvents. Relieve system pressure and isolate the service point before removing existing seals or installing fabricated replacements. Follow applicable mechanical codes and equipment manufacturer guidelines for seal material selection.
