The Value Collection BDNA-9970 is a Dash 005 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 3/32 inches inside diameter and 1/16 inch thick. NBR compound provides reliable resistance to petroleum-based fluids, making this O-ring a standard choice for sealing applications in HVAC, plumbing, and general mechanical assemblies. Licensed tradespeople and maintenance technicians use these small-diameter O-rings to seal fittings, valves, and low-pressure hydraulic or pneumatic connections where dimensional precision and chemical compatibility with oils and fuels are required.
This O-ring is suited for residential and light commercial service work involving gas valves, refrigeration fittings, plumbing shut-off valves, and similar components that call for an inch-system Dash 005 seal. Its compact geometry fits tight-tolerance grooves in standard AN and inch-series hardware. NBR material performs across a broad service temperature range, making it appropriate for both indoor mechanical rooms and field service environments. Minimum order quantity is 50 pieces, sold as a single-unit package quantity.
Designed as a standard Dash 005 inch-series O-ring replacement for valves, fittings, and mechanical assemblies that specify NBR compound and round cross section geometry.
O-ring installation should be performed by a qualified technician after depressurizing the system and relieving all fluid or gas pressure. Lightly lubricate the O-ring with a compatible grease or oil before seating it in the groove to prevent twisting or tearing during assembly. Inspect the groove for burrs or corrosion before installation. Follow applicable codes and equipment manufacturer torque specifications for the fitting or valve being serviced.
