Value Collection BDNA-MP9976 O-ring Dash 011 Nbr

Product Description

The VALUE COLLECTION BDNA-MP9976 is a Dash 011 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 5/16 inches inside diameter and 1/16 inches in thickness, conforming to standard inch-series O-ring sizing. NBR compound delivers reliable resistance to petroleum-based fluids, oils, and fuels, making this seal a dependable choice for hydraulic, pneumatic, and fluid-handling assemblies. A durometer rating of 70 Shore A provides a balance of pliability and compression resistance suited to moderate-pressure sealing applications. Plumbers, HVAC technicians, and mechanical contractors regularly use Dash 011 O-rings as replacement seals in valves, fittings, and service connections.

This O-ring is suited for residential and light commercial plumbing, HVAC refrigerant circuit components, and general mechanical fluid systems where an inch-series NBR seal is required. Common install scenarios include valve stem seals, union connections, flare adapters, and service port fittings. The Dash 011 designation is a widely recognized standard size, allowing straightforward cross-referencing in the field when replacing worn or damaged seals during routine service calls or equipment repairs.

Key Features

• Dash 011 standard inch-series sizing: 5/16 inches inside diameter, 1/16 inches thickness
• Nitrile Butadiene Rubber (NBR) material resists petroleum oils, hydraulic fluids, and fuels
• 70 Shore A durometer for reliable compression and moderate-pressure sealing
• Round cross section ensures consistent seating in standard O-ring grooves
• Inch-system dimensioning for direct compatibility with standard SAE and inch-series hardware

Compatibility

Designed as a standard Dash 011 inch-series replacement O-ring for use in valves, fittings, and fluid-handling components requiring an NBR seal with 5/16 inch inside diameter and 1/16 inch cross-section thickness.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or qualified mechanical tradespeople. Shut off and depressurize the system fully before removing any fitting or valve containing this seal. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent tearing during assembly. Do not stretch the O-ring beyond its natural diameter when installing, and inspect the groove for nicks or debris that could compromise the seal.
