Value Collection BDNA--9988-3 O-ring Dash 122 Nbr

Product Description

The VALUE COLLECTION BDNA--9988-3 is a Dash 122 O-ring with a 1-1/8 inch inside diameter and a 3/32 inch cross-section thickness, manufactured from Nitrile Butadiene Rubber (NBR) with a 70 durometer hardness rating. NBR compounds offer solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making this O-ring a reliable sealing choice in fluid-handling systems. The round cross-section profile seats evenly in standard O-ring grooves. Plumbers, HVAC technicians, and equipment service professionals install this type of seal in pumps, valves, fittings, and manifold assemblies where a positive static or dynamic fluid seal is required.

This O-ring is suited for residential and light commercial plumbing, HVAC refrigerant-adjacent fluid circuits, pool and spa equipment, and general industrial fluid-handling applications. It is dimensioned to the Dash 122 standard, allowing straightforward cross-reference and replacement in any system or assembly that calls out a Dash 122 seal. The NBR compound performs across a broad temperature range typical of water, oil, and gas service applications common to trade work. This SKU is sold as a single piece with a minimum order quantity of 25 units.

Compatibility

Designed as a standard Dash 122 replacement O-ring for any pump, valve, fitting, or manifold assembly specifying a 1-1/8 inch ID, 3/32 inch thick NBR O-ring in inch-system sizing.

Installation Notes

Depressurize and drain the system before removing the old O-ring and installing the replacement. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent tearing during installation. Inspect the groove for nicks, corrosion, or debris that could compromise the seal. Follow the equipment manufacturer's torque and assembly specifications for the surrounding fitting or cap.
