Value Collection BDNA--9984-11 O-ring Dash 133 Nbr

Product Description

The VALUE COLLECTION BDNA--9984-11 is a Dash 133 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 1-13/16 inches inside diameter and 3/32 inches thick, with a durometer rating of 70 Shore A. NBR compounds offer solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making this O-ring well suited for sealing applications in plumbing, HVAC, and fluid system assemblies. Licensed plumbers, HVAC technicians, and industrial maintenance professionals commonly specify this seal size for service and repair work on fluid-handling components.

This O-ring is used in residential and light commercial applications where a standard inch-series Dash 133 seal is required. Typical install scenarios include pump housings, valve bodies, refrigeration fittings, and hydraulic or pneumatic connectors that call for a 1-13/16 inches ID round-cross-section seal. The 70 durometer NBR material performs reliably across a wide temperature range and handles exposure to water, oils, and many common refrigerants found in HVAC and plumbing systems.

Key Features

• Dash 133 standard inch-series sizing: 1-13/16 inches ID, 3/32 inches thick
• Nitrile Butadiene Rubber (NBR) material resists petroleum oils, hydraulic fluids, and water
• 70 Shore A durometer provides a firm yet compressible seal under typical clamping loads
• Round cross section seats cleanly in standard O-ring grooves without orientation concerns
• Lightweight at 0.01 pounds, suitable for high-quantity service kit builds

Compatibility

Designed as an OEM-style replacement or service seal for any fluid system component calling for a Dash 133 inch-series O-ring in Nitrile Butadiene Rubber.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Before replacing an O-ring, isolate and depressurize the system and shut off fluid supply at the nearest isolation valve. Lubricate the O-ring with a compatible lubricant before seating to prevent tearing during assembly. Inspect the mating groove for nicks or corrosion that could compromise the seal before installing the new ring.
