Value Collection 0284187 Buna-n Round Cord Stock 3/16 in

Product Description

The VALUE COLLECTION 0284187 is a Buna-N (nitrile rubber) round cord stock supplied in a 100-foot standard coil. Buna-N cord stock is a flexible elastomeric sealing material used to fabricate custom O-rings, gaskets, and seals in the field or shop. The cord measures 3/16 inch (0.188 inches) in diameter with a tolerance of plus or minus 0.008 inches. This material is well suited for applications involving petroleum-based fluids, hydraulic oils, and fuels. Plumbers, HVAC technicians, and industrial maintenance trades use Buna-N cord stock when a standard O-ring size is unavailable and a field-cut seal is required.

Buna-N round cord stock is used across residential and commercial plumbing, HVAC, refrigeration, and light industrial equipment. Common applications include sealing threaded fittings, valve bodies, pump housings, and compressor covers where oil or fuel contact is expected. The 100-foot coil length provides enough material for multiple cuts, making it practical for service vans and shop inventory. This item ships as a single coil and is sold in minimum order quantities of 25 units.

Compatibility

Designed as a general-purpose field sealing material for use in plumbing, HVAC, refrigeration, and industrial maintenance applications where a 3/16-inch diameter Buna-N cord seal is required.

Installation Notes

Cord stock seals are typically installed by plumbers, HVAC technicians, or industrial mechanics. Relieve system pressure and shut off fluid supply before opening any fitting or housing where the seal will be placed. Cut the cord to the required circumference using a sharp blade and a straight, perpendicular cut, then join the ends with an appropriate Buna-N splice adhesive for a proper seal. Follow all applicable local codes and equipment manufacturer guidelines when using field-fabricated seals in pressurized systems.
