Value Collection BDNA--9993-5 O-ring Dash 232 Nbr

Product Description

The VALUE COLLECTION BDNA--9993-5 is a Dash 232 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 2-3/4 inches inside diameter and 1/8 inch thick, with a durometer rating of 70 Shore A. NBR compound provides reliable resistance to petroleum-based fluids, making this O-ring a standard choice for sealing applications in HVAC, plumbing, and hydraulic systems. Licensed plumbers, HVAC technicians, and mechanical contractors install O-rings like this during equipment assembly, valve repair, and pump servicing where a fluid-tight static or dynamic seal is required.

This O-ring is suited for residential and light commercial applications where an inch-series Dash 232 seal is specified. Typical use cases include sealing flanged connections, pipe unions, valve bodies, and pump housings that handle water, oil, or air. The 70 durometer hardness balances flexibility and compression resistance across a broad range of groove-fit applications. This part ships in single-unit quantities with a minimum order of 25 units per order.

Key Features

• Dash 232 inch-series sizing: 2-3/4 inches inside diameter, 1/8 inch thickness
• Nitrile Butadiene Rubber (NBR) material resists petroleum-based fluids and hydraulic oils
• Round cross section ensures consistent seating in standard O-ring grooves
• 70 Shore A durometer provides balanced flexibility and compression resistance
• Inch system of measurement for direct compatibility with standard SAE groove specifications

Compatibility

Designed as a standard inch-series replacement O-ring for any application calling out a Dash 232 cross section in NBR compound, including valve bodies, pump housings, and pipe union fittings in HVAC, plumbing, and fluid-handling systems.

Installation Notes

Power down or depressurize the system completely before replacing any O-ring in a pressurized fluid or gas circuit. Lubricate the O-ring lightly with a compatible grease or fluid before seating to prevent tearing during installation. Inspect the groove for nicks, corrosion, or debris that could compromise the seal. Follow applicable plumbing or mechanical codes, such as IPC or ASME standards, for the specific system being serviced.
