It is manufactured from Nitrile Butadiene Rubber (NBR) with a durometer hardness of 70, making it well suited for petroleum-based fluids, water, and many common refrigerants. The inside diameter measures 1-9\/16 inches with a 3\/32-inch cross-section thickness and a round cross-section profile. Plumbers, HVAC technicians, and industrial maintenance professionals install this ring as a compression seal at fittings, valves, caps, and ported connections.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is sized to the standard Dash 129 designation within the inch measurement system. It is a common replacement seal for valves, pipe unions, ball valves, manifold ports, and service fittings found in residential and light commercial plumbing and HVAC equipment.
