Value Collection BDNA-MP9973 O-ring Dash 008 Nbr

Product Description

The VALUE COLLECTION BDNA-MP9973 is a Dash 008 O-ring used to create leak-proof seals in fluid and pneumatic systems. Molded from Nitrile Butadiene Rubber (NBR) with a 70 durometer hardness rating, it provides solid resistance to oils, fuels, and hydraulic fluids. The inside diameter measures 3/16 inches and the cross-section thickness is 1/16 inches, matching the Dash 008 standard sizing designation. The round cross-section profile seats evenly in standard O-ring grooves. Plumbers, HVAC technicians, and industrial mechanics commonly install this type of seal during equipment assembly, valve service, and fitting replacement work.

This O-ring is suited for use in residential and light commercial plumbing, HVAC refrigerant-side and water-side connections, pneumatic fittings, and hydraulic assemblies where NBR material is compatible with the working fluid. The Dash 008 designation is a widely recognized inch-system standard, making this ring a straightforward dimensional match wherever that size is specified. NBR compound performs reliably across a broad range of petroleum-based fluid applications and is a common go-to material for general-purpose sealing tasks in the trades.

Key Features

• Dash 008 standard sizing — 3/16 inch inside diameter, 1/16 inch cross-section thickness
• Nitrile Butadiene Rubber (NBR) construction with 70 durometer hardness for firm, reliable seating
• Round cross-section profile for consistent groove contact and even compression
• Inch-system measurement — direct dimensional replacement for Dash 008 spec calls
• Compatible with petroleum-based oils, hydraulic fluids, and fuels in typical operating environments

Compatibility

Designed as a standard Dash 008 inch-system O-ring for use in plumbing, HVAC, pneumatic, and hydraulic assemblies where Nitrile Butadiene Rubber material and Dash 008 dimensional specifications are required.

Installation Notes

Shut off fluid supply and relieve system pressure completely before removing old seals or disassembling fittings. Inspect the O-ring groove for burrs, scoring, or debris before installing the new ring. Applying a thin film of compatible lubricant to the O-ring prior to installation helps prevent tearing during assembly and promotes even seating. Installation is typically performed by licensed plumbers, HVAC technicians, or qualified mechanics depending on the application.
