Value Collection ZBD9994-4X O-ring Dash 332 Nbr

Product Description

The VALUE COLLECTION ZBD9994-4X is a Dash 332 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 2.375 inches inside diameter, 2.75 inches outside diameter, and 0.1875 inches thick. NBR compound delivers reliable sealing performance across a wide service temperature range, rated from -40 degrees F to 275 degrees F. With a Shore A hardness of 70, this O-ring provides firm compression and consistent sealing force under pressure. It is installed by plumbers, HVAC technicians, hydraulic equipment technicians, and industrial maintenance professionals wherever a Dash 332 NBR O-ring is required.

This O-ring is suited for use in fluid and gas sealing applications across plumbing, HVAC, hydraulic, and pneumatic systems. Its NBR construction makes it compatible with petroleum-based oils, fuels, water, and many common hydraulic fluids. It is a standard Dash 332 size, making it a direct fit in any gland or groove dimensioned to that specification. Typical applications include pump seals, valve stems, pipe fittings, and mechanical assemblies requiring a durable elastomeric seal.

Installation Notes

Plumbers, HVAC technicians, and maintenance mechanics install this O-ring as part of routine seal replacement or component assembly. Before installation, shut off and depressurize the system being serviced and clean the seating surface of any debris or old sealant material. Apply a compatible lubricant to the O-ring to ease installation and prevent tearing during assembly. Do not overstretch or twist the O-ring during placement, as distortion compromises sealing integrity.
