The VALUE COLLECTION BDNA--9977-4 is a Dash 014 O-ring with a 0.5 inch inside diameter and a 0.0625 inch (1/16 inch) round cross-section thickness. Made from Nitrile Butadiene Rubber (NBR) with a 70 durometer hardness rating, this O-ring provides reliable static and dynamic sealing in fluid and pneumatic systems. NBR compound offers solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making it a go-to choice for plumbing, HVAC, and industrial maintenance applications. Licensed plumbers, HVAC technicians, and industrial mechanics install this style of O-ring during equipment assembly, valve service, and fitting repairs.
This Dash 014 NBR O-ring is suited for residential and light commercial plumbing systems, HVAC refrigerant line fittings, hydraulic assemblies, and pneumatic circuits that operate with petroleum-based or water-based media. The inch-system sizing follows the standard AS568 dash numbering convention. It is sold individually per package, with a minimum order quantity of 50 units, making it appropriate for shop stock, service van inventory, or MRO replenishment programs where technicians encounter this size frequently.
Designed as an OEM-style replacement or service-stock O-ring for valves, fittings, and fluid-handling components that call for a Dash 014 NBR O-ring in inch-system sizing.
Installation is typically performed by licensed plumbers, HVAC technicians, or industrial mechanics during valve overhaul, fitting assembly, or pump service. Always depressurize and isolate the system before removing existing O-rings. Inspect the mating groove for burrs or scoring before seating the new O-ring, and apply a compatible lubricant to reduce installation stress and prevent twisting. Follow applicable codes such as IPC or IFGC for plumbing and gas system work.
