-113 BLACK BUNA 90D O-RING

The H90113 is an AS568-113 black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 0.549 in (13.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.755 in (19.18 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to petroleum-based oils, greases and lubricants, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with automotive brake fluid or ozone and direct sunlight.

Common environments for this compound include hydraulic and pneumatic systems, agricultural equipment, and general industrial maintenance.
