Value Collection 0M284B4 Buna-n Round Cord Stock

Product Description

The VALUE COLLECTION 0M284B4 is a Buna-N (nitrile rubber) round cord stock supplied in a 100-foot standard coil. Buna-N material offers solid resistance to petroleum-based oils, fuels, and many hydraulic fluids, making this cord stock a practical choice for fabricating custom O-rings, sealing gaskets, and compression seals in the field or shop. The round cross-section profile is consistent throughout the coil length, supporting reliable sealing performance when cut to a custom length and bonded or installed into a groove. Technicians across plumbing, HVAC, and industrial maintenance trades keep this cord on hand for on-demand seal fabrication.

This cord stock is suited for applications requiring a field-made or custom-length seal where a standard O-ring size is not available. Common uses include sealing grooves in hydraulic cylinders, pump housings, valve bodies, and pipe fittings that handle petroleum-based media. The 100-foot coil length provides enough material for multiple repair or fabrication jobs without the need to reorder frequently. It is appropriate for both shop-bench fabrication work and on-site field repairs where custom seals are needed.

Key Features

• Buna-N (nitrile rubber) material provides resistance to petroleum-based oils and fuels
• Round cross-section profile for consistent fit in standard cord-seal grooves
• 100-foot coil length supports multiple custom-cut seals per coil
• Compatible with field-bonding or mechanical splice techniques for closed-loop O-ring fabrication
• Suitable for hydraulic, pneumatic, and plumbing sealing applications involving oil or fuel media

Compatibility

Designed as a general-purpose Buna-N round cord stock for use in any application requiring a custom-length nitrile sealing element in petroleum-based fluid systems.

Installation Notes

A licensed mechanic, plumber, or qualified technician should confirm the groove dimensions and media compatibility before fabricating and installing a custom seal from this cord stock. Depressurize and drain the system fully before removing existing seals or installing new ones. Use a clean, sharp blade to cut cord ends squarely, and follow the adhesive or splice fitting manufacturer instructions when forming a closed-loop O-ring. Verify the finished seal seats evenly in the groove before returning the system to service.
