Value Collection BDNA--9977-13 O-ring Dash 033 Nbr

Product Description

The VALUE COLLECTION BDNA--9977-13 is a Dash 033 O-ring with a 2-inch inside diameter and a 1/16-inch round cross section, manufactured from Nitrile Butadiene Rubber (NBR). With a durometer rating of 70, this O-ring delivers firm, reliable sealing under moderate compression. NBR material provides good resistance to petroleum-based fluids, making it a common choice in hydraulic, pneumatic, plumbing, and HVAC fluid-handling assemblies. Licensed plumbers, HVAC technicians, and maintenance professionals regularly stock Dash 033 O-rings for valve, fitting, and pump service work.

This O-ring is suited for use in residential and light commercial systems where a standard inch-measurement Dash 033 seal is required. Typical applications include pump housings, ball valves, unions, manifolds, and fluid-line fittings that handle water, oil, or air at moderate temperatures and pressures. The NBR compound makes it appropriate for systems that contact mineral oils, fuels, and many hydraulic fluids, though it is not recommended for exposure to ozone, ketones, esters, or chlorinated solvents.

Key Features

• Dash 033 designation — 2-inch inside diameter with 1/16-inch cross section thickness
• Round cross section for uniform sealing contact and consistent groove fit
• Nitrile Butadiene Rubber (NBR) compound — good resistance to petroleum-based fluids and water
• 70 durometer hardness — firm seal under standard compression loads
• Inch-system dimensioning for direct use in standard SAE and imperial groove specifications

Compatibility

Designed as a standard Dash 033 inch-series O-ring replacement for valves, pumps, fittings, and fluid-handling components that call out a 2-inch ID, 1/16-inch cross section NBR seal.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Always depressurize and isolate the system before removing the old O-ring and seating the replacement. Lightly lubricate the O-ring with a compatible lubricant — use a petroleum-based grease only on systems where NBR contact with that fluid is acceptable — to ease installation and reduce the risk of tearing during assembly. Inspect the groove for burrs or corrosion before seating, and avoid rolling or twisting the O-ring as it is placed.
