H90M2.4X25.3 is a black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 25.3 mm (0.996 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 30.1 mm (1.19 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Buna-N (Nitrile) is valued for strong abrasion and tear resistance, low compression set under sustained load. This material stands up to propane and butane, greases and lubricants, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in automotive brake fluid or polar solvents.
Common environments for this compound include agricultural equipment, construction equipment, and general industrial maintenance.
