-010 BLACK BUNA 70D O-RING

APG stocks the H70010, an AS568-010 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.239 in (6.07 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.379 in (9.63 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, low compression set under sustained load. It resists water, propane and butane, and many alcohols. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ketones or ozone and direct sunlight will shorten service life.

It sees regular use in construction equipment, agricultural equipment, and automotive.

H70010 ships individually. Unit weight is approximately 0.0755 g and nominal inside diameter is listed as 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
