Value Collection BDNA--9977-6 O-ring Dash 022 Nitrile

Product Description

The VALUE COLLECTION BDNA--9977-6 is a Dash 022 O-ring used to create fluid-tight seals in hydraulic, pneumatic, plumbing, and HVAC systems. Molded from Nitrile Butadiene Rubber (Buna-N), it features a round cross section with a 1 inch inside diameter and a 1/16 inch thickness. The material delivers reliable resistance to oils, fuels, and common refrigerants, making it a dependable choice for sealing fittings, valves, and connectors in trade applications. With a durometer rating of 70, the ring offers a firm yet compressible seal that maintains integrity under typical system pressures. Plumbers, HVAC technicians, and industrial maintenance professionals install this O-ring as a standard service component.

This O-ring is suited for use in residential and light commercial systems where inch-measurement sealing components are required. Typical applications include sealing threaded or push-fit connections in water lines, refrigerant circuits, compressed-air systems, and hydraulic assemblies. Its Buna-N compound performs well with petroleum-based fluids and water, covering a broad range of service environments encountered in plumbing, HVAC, and pool equipment maintenance. The Dash 022 designation is a standard sizing reference used across many OEM and aftermarket component lines.

Key Features

• Buna-N (Nitrile Butadiene Rubber) construction resists oils, fuels, and common refrigerants
• 1 inch inside diameter with standard Dash 022 sizing for broad interchangeability
• 1/16 inch cross-section thickness with round profile for consistent compression sealing
• Durometer 70 hardness balances compressibility and pressure resistance
• Inch-system dimensions suit standard SAE and plumbing-trade fittings

Compatibility

Designed as a standard Dash 022 inch-series O-ring replacement for use in hydraulic, pneumatic, plumbing, and HVAC sealing applications requiring a 1 inch inside diameter Buna-N component.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize and, where applicable, recover refrigerant or shut off fluid supply before disassembling fittings or valve bodies. Lubricate the O-ring lightly with a compatible fluid or assembly lubricant before seating to prevent tearing during installation. Follow applicable codes such as the IPC or IFGC for system-specific sealing requirements.
