Part number H2X37.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 37.5 mm (1.476 in), a cross section of 2 mm (0.079 in), and an outside diameter of 41.5 mm (1.63 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. This item is further identified as Metric O-RING, JIS S38.
The material holds up against petroleum-based oils, many alcohols, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C).
You will find this material specified across construction equipment, general industrial maintenance, and hydraulic and pneumatic systems.
