5.7MM CS X 134.3MM ID BLACK BUNA 90D

APG stocks the H90M5.7X134.3, a black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 134.3 mm (5.287 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 145.7 mm (5.74 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to water, many alcohols, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with automotive brake fluid or polar solvents.

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