Value Collection BDNA-MP9981 O-ring Dash 113 Nbr

Product Description

The VALUE COLLECTION BDNA-MP9981 is a Dash 113 O-ring made from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 9/16 inches inside diameter and 3/32 inches thick, with a durometer rating of 70 Shore A. NBR compound provides reliable resistance to petroleum-based fluids, making this O-ring well suited for sealing applications in HVAC, plumbing, and fluid-handling systems. Licensed tradespeople and maintenance technicians stock these for routine service calls where sealing integrity is critical to system performance.

This O-ring is used in residential and light commercial applications wherever a Dash 113 standard-size seal is specified. Typical install scenarios include valve stems, fittings, pump housings, and refrigerant service ports that require a 9/16-inch ID round-cross-section seal. The 70-durometer NBR construction holds up well in environments exposed to oils, fuels, and water-based fluids across a broad service temperature range.

Key Features

• Dash 113 standard sizing for drop-in replacement use
• 9/16 inch inside diameter with 3/32 inch cross-section thickness
• Round cross section for consistent seating in standard grooves
• 70 Shore A durometer for balanced flexibility and compression resistance
• Nitrile Butadiene Rubber (NBR) construction resists petroleum-based fluids and water
• Inch measurement system — compatible with standard SAE groove specifications

Compatibility

Designed as a standard Dash 113 O-ring replacement for any application specifying a 9/16 inch ID, 3/32 inch thick, round-cross-section NBR seal in inch-dimensioned groove patterns.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or qualified maintenance personnel. Always depressurize and isolate the system before removing the old O-ring to prevent fluid release. Lightly lubricate the O-ring with a compatible fluid or grease prior to seating to avoid tearing during installation. Inspect the mating groove for burrs or corrosion before fitting the new seal.
