-920 BLACK BUNA 70D O-RING

The H70920 is an AS568-920 black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 1.475 in (37.47 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 1.711 in (43.46 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is valued for low compression set under sustained load, strong abrasion and tear resistance. It resists water, propane and butane, and greases and lubricants. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where strong acids or polar solvents are present.

It sees regular use in automotive, general industrial maintenance, and agricultural equipment.

H70920 ships individually. Unit weight is approximately 0.0011 g and nominal inside diameter is listed as 1 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
