This o-ring is supplied in AS568-007 black Buna-N (Nitrile) 90 Shore A built to an inside diameter of 0.145 in (3.68 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.285 in (7.24 mm), catalogued under part number H90007. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
It resists many alcohols, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers an economical choice for high-volume maintenance programs and low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or strong acids.
You will find this material specified across agricultural equipment, fluid power, and construction equipment.
