The VALUE COLLECTION ZBD9984-22 is a Dash 144 nitrile butadiene rubber (NBR) O-ring used to create static or dynamic fluid seals in hydraulic, pneumatic, plumbing, and HVAC systems. It measures 2.5 inches inside diameter, 2.69 inches outside diameter, and 0.0937 inches thick with a round cross section. Shore hardness is rated at 70, placing it in the hard range suitable for moderate-pressure sealing applications. This O-ring is installed by plumbers, HVAC technicians, and industrial maintenance technicians wherever a reliable, temperature-resistant elastomeric seal is required.
This O-ring is suited for residential and commercial applications involving water, oil, fuel, and many common hydraulic fluids. Its NBR compound resists petroleum-based fluids and performs across a wide service temperature range from -40 degrees F to 275 degrees F. Typical install scenarios include pump seals, valve bodies, pipe fittings, manifold ports, and refrigeration or HVAC component housings where a Dash 144 cross-section O-ring is specified.
Designed as an OEM-style replacement O-ring for any application requiring a Dash 144 NBR O-ring with a 2.5 inches inside diameter and round cross section.
Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Always depressurize and isolate the system before removing the existing O-ring. Lightly lubricate the O-ring with a compatible fluid or grease before seating it to prevent rolling or tearing during assembly. Verify groove dimensions match the Dash 144 cross-section specification before installation to ensure proper compression and seal integrity.
