10MM CS X 45MM ID BLACK BUNA 70D

Part number H10X45 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 45 mm (1.772 in), a cross section of 10 mm (0.394 in), and an outside diameter of 65 mm (2.56 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to propane and butane, petroleum-based oils, 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).

It sees regular use in fluid power, construction equipment, and general industrial maintenance.

Stocked as H10X45 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
