Ordered as H1.2X5, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 5 mm (0.197 in), a cross section of 1.2 mm (0.047 in), and an outside diameter of 7.4 mm (0.29 in). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Buna-N (Nitrile) offers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Expect good resistance to greases and lubricants, petroleum-based oils, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or automotive brake fluid will shorten service life.
You will find this material specified across agricultural equipment, fluid power, and automotive.
H1.2X5 ships individually. Unit weight is approximately 0.0001 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
