Value Collection 0296313 Buna-n Square Cord Stock

Product Description

The VALUE COLLECTION 0296313 is a Buna-N square cord stock supplied in a 200-foot standard coil. Buna-N, also known as nitrile rubber, is a synthetic elastomer widely used for sealing and gasketing applications where resistance to petroleum-based fluids, oils, and fuels is required. The cord measures 0.313 inches square in cross-section and is sold per coil. Technicians and maintenance professionals cut this cord to length in the field, making it a practical material for fabricating custom O-ring replacements, gaskets, and seals on pumps, valves, and fluid-handling equipment.

This square cord stock is suited for industrial, commercial, and trade applications including HVAC, plumbing, and general mechanical service. The square profile seats firmly in grooves where a round cross-section may roll or shift, making it a reliable choice for face seals, dovetail grooves, and static sealing applications. Plumbers, HVAC technicians, and maintenance mechanics commonly stock this material for on-the-spot seal fabrication where a standard O-ring size is not available.

Key Features

• Buna-N nitrile rubber construction offers strong resistance to petroleum oils, hydraulic fluids, and fuels
• Square cross-section profile seats securely in machined grooves without rolling
• 0.313-inch square size accommodates a wide range of standard groove dimensions
• 200-foot coil length allows field cutting to any required seal perimeter
• Inch measurement system for direct compatibility with standard US tooling and groove specifications

Compatibility

Designed as a general-purpose sealing cord for static sealing applications in pumps, valves, manifolds, and fluid-handling assemblies requiring a 0.313-inch square nitrile cord stock.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance mechanics. Before replacing any seal or gasket, shut off and depressurize the system completely. Cut the cord to the required length using a sharp blade for a clean, square end, then join the ends with a compatible nitrile adhesive if a closed-loop seal is needed. Do not overstretch the cord during installation, as this will reduce the cross-sectional area and compromise the seal.
