Value Collection ZBD9984-20 O-ring Dash 142 Nbr 2.375 in Id

Product Description

The VALUE COLLECTION ZBD9984-20 is a Dash 142 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 2.375 inches inside diameter, 2.5625 inches outside diameter, and 0.09375 inches thick. With a Shore A hardness of 70 and a working temperature range of -40 degrees F to 275 degrees F, this O-ring is suited for static and dynamic sealing applications in fluid and pneumatic systems. It is installed by plumbers, HVAC technicians, and general mechanical trades wherever a Dash 142 NBR seal is specified.

This O-ring fits applications requiring a standard Dash 142 size seal in systems handling petroleum-based fluids, water, and many common hydraulic fluids. The NBR compound provides solid resistance to oil, fuel, and grease, making it a standard choice in plumbing assemblies, HVAC refrigerant-adjacent components, compressor housings, and general industrial fittings. It is sold in individual units with a minimum order quantity of 25 pieces.

Key Features

• Dash 142 standard sizing: 2.375 inches ID x 2.5625 inches OD x 0.09375 inches thick
• Nitrile Butadiene Rubber (NBR) compound for compatibility with oils, fuels, and water-based media
• Shore A hardness of 70 for reliable compression and sealing under typical system pressures
• Operating temperature range of -40 degrees F to 275 degrees F
• Round cross section for consistent groove seating and uniform compression
• Lightweight at 0.01 pounds per unit

Compatibility

Designed as an OEM-style replacement or standard-fitment O-ring for any assembly specifying a Dash 142 NBR O-ring with a round cross section.

Installation Notes

Install and service performed by licensed plumbers, HVAC technicians, or qualified mechanical trades. Depressurize and drain the system before removing or installing O-rings. Inspect the groove for burrs, corrosion, or debris before seating the new O-ring. A light application of a compatible lubricant aids installation and reduces the risk of damage during assembly.
