The H90916 is an AS568-916 black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 1.171 in (29.74 mm), a cross section of 0.116 in (2.95 mm), and an outside diameter of 1.403 in (35.64 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
It resists many alcohols, petroleum-based oils, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with polar solvents or automotive brake fluid.
You will find this material specified across general industrial maintenance, fluid power, and construction equipment.
Stocked as H90916 and sold individually. Unit weight is approximately 0.932 g and nominal inside diameter is listed as 1 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
