Product Specification

-
Part number H5X225 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 225 mm (8.858 in), a cross section of 5 mm (0.197 in), and an outside diameter of 235 mm (9.25 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is widely chosen for low compression set under sustained load, strong abrasion and tear resistance. It resists hydraulic fluids, propane and butane, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ozone and direct sunlight or strong acids will shorten service life.

It sees regular use in fluid power, hydraulic and pneumatic systems, and automotive.

H5X225 ships individually. Unit weight is approximately 17.333 g. Check the compound against your process media, pressure and temperature before committing to a design.
