Value Collection 0284139 Buna-n Round Cord Stock

Product Description

The VALUE COLLECTION 0284139 is a Buna-N round cord stock supplied in a 100-foot standard coil length. Buna-N, also known as nitrile rubber, is a synthetic elastomer widely specified for its resistance to petroleum-based oils, fuels, and hydraulic fluids. This cord stock is used to fabricate custom O-rings, gaskets, and seals in the field or shop. Technicians cut the cord to the required length, join the ends with an appropriate adhesive, and produce a seal sized to fit non-standard grooves or replace an unavailable formed ring. The round cross-section suits standard O-ring groove profiles.

This cord stock is a practical addition to any service van or shop stocked for plumbing, HVAC, or industrial maintenance work. It is well suited for applications involving contact with mineral oils, hydraulic fluids, and water. The 100-foot coil provides enough material for multiple field repairs or shop fabrications. It is commonly used in low-pressure sealing applications where a molded O-ring of the correct size is not on hand.

Key Features

• Buna-N nitrile rubber construction offers strong resistance to petroleum oils, fuels, and hydraulic fluids
• Round cross-section fits standard O-ring groove geometries
• 100-foot coil length supports multiple fabrications from a single stock piece
• Field-cuttable design allows custom seal sizing without ordering a molded part
• Metric measurement system designation for cross-referencing with metric groove specifications

Compatibility

Designed as a field-fabrication cord stock for creating custom O-rings and seals in plumbing, HVAC, and general industrial sealing applications where a standard molded O-ring is unavailable or a non-standard groove size requires a custom fit.

Installation Notes

Cut the cord to the required circumference using a sharp blade, ensuring a clean, square cut on both ends before joining. A licensed plumber, HVAC technician, or qualified maintenance mechanic should verify that the cord diameter matches the groove dimensions before fabricating a seal. De-energize and depressurize the system fully before removing any existing seal and installing a fabricated replacement. Follow applicable codes such as IPC or IFGC when using field-fabricated seals in regulated piping systems.
