-009 BLACK BUNA 70D O-RING

APG stocks the H70MD009, an AS568-009 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 0.208 in (5.28 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.348 in (8.84 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists water, propane and butane, and petroleum-based oils. Buna-N (Nitrile) is valued for low compression set under sustained load, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ozone and direct sunlight or strong acids.

The compound is metal detectable for HACCP and foreign-body control programs. You will find this material specified across automotive, fluid power, and general industrial maintenance.

H70MD009 ships individually. Nominal inside diameter is listed as 7/32 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.
