Value Collection BDNA--9988-5 O-ring Dash 124 Nbr

Product Description

The VALUE COLLECTION BDNA--9988-5 is a Dash 124 nitrile butadiene rubber (NBR) O-ring used for fluid and gas sealing in plumbing, HVAC, and hydraulic applications. It features a 1-1/4 inch inside diameter and a 3/32 inch cross-section thickness with a round cross-section profile. The durometer rating is 70, indicating a firm yet flexible seal suitable for moderate-pressure environments. NBR material provides solid resistance to petroleum-based oils, fuels, and common hydraulic fluids. Plumbers, HVAC technicians, and equipment service pros install this type of O-ring during system maintenance, valve service, and fitting replacement.

This O-ring is suited for residential and light commercial applications where an inch-system Dash 124 seal is required. Typical installations include valve bodies, pump housings, pipe unions, refrigerant service fittings, and hydraulic line connections. The NBR compound performs across a broad range of temperatures encountered in standard HVAC and plumbing service environments. This SKU is sold individually, with a minimum order quantity of 25 units.

Key Features

• Dash 124 standard sizing: 1-1/4 inch inside diameter with 3/32 inch cross-section thickness
• Nitrile butadiene rubber (NBR) compound resists petroleum oils, hydraulic fluids, and fuels
• Round cross-section profile for consistent groove seating and even compression
• 70 durometer hardness balances flexibility and pressure resistance
• Inch-system measurement for straightforward fitment in standard U.S. components

Compatibility

Designed as a standard Dash 124 inch-series O-ring replacement for valves, fittings, pump housings, and hydraulic or plumbing components requiring a 1-1/4 inch ID NBR seal.

Installation Notes

Licensed plumbers and HVAC technicians typically perform O-ring replacement during valve, pump, or fitting service. Always depressurize the system and isolate the fluid supply before removing any component containing an O-ring. Inspect the mating groove for nicks, burrs, or debris before seating the new ring, and apply a compatible lubricant to ease installation and prevent pinching. Follow applicable IPC or IFGC guidelines for the system type being serviced.
