Value Collection 0284312 Buna-n Round Cord Stock 5/16 in

Product Description

The VALUE COLLECTION 0284312 is a Buna-N nitrile rubber round cord stock supplied in a 100-foot standard coil. Buna-N is a petroleum-resistant synthetic elastomer widely used in sealing, gasketing, and O-ring fabrication for HVAC, plumbing, and industrial fluid-handling applications. This cord measures 0.313 inches (5/16 inch) in diameter and is cut from extruded round stock, making it suitable for custom-length sealing applications where standard pre-formed gaskets are not practical. Technicians and mechanics use this type of cord stock to fabricate face seals, groove seals, and other compression gaskets in the field.

Buna-N round cord stock is commonly used in residential and commercial HVAC systems, plumbing assemblies, pump housings, and valve bodies where oil, fuel, or water resistance is required. The 100-foot coil length provides enough material for multiple jobs or bulk shop use. Typical applications include sealing refrigerant-adjacent components, water-side plumbing fittings, and light industrial fluid connections. This cord is cut to length using a utility knife or sharp blade at the point of installation.

Key Features

• Buna-N (nitrile) material resists petroleum oils, fuels, and water
• Round cross-section cord at 0.313 inches (5/16 inch) diameter
• 100-foot coil length supports bulk fabrication and multiple service calls
• Inch measurement system for compatibility with standard trade tooling and sizing charts
• Flexible cord stock allows field-cut custom gaskets and seals

Compatibility

Designed as a general-purpose round cord stock for use wherever Buna-N nitrile elastomer and a 5/16-inch diameter round profile meet the application requirements. No specific equipment model compatibility is stated by the manufacturer for this stock material.

Installation Notes

Cut cord stock to the required length using a sharp utility knife on a clean, flat surface to ensure a square, gap-free joint. When forming a closed-loop seal, cement the cut ends with nitrile-compatible adhesive and allow full cure time before pressurizing the assembly. Shut off all fluid supply and relieve system pressure before removing any existing seals or gaskets. Follow applicable plumbing or mechanical codes for the jurisdiction in which the work is performed.
