Product Specification

-
H4X94 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 94 mm (3.701 in), a cross section of 4 mm (0.157 in), and an outside diameter of 102 mm (4.02 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) delivers strong abrasion and tear resistance, reliable performance in both static and dynamic service. The material holds up against petroleum-based oils, many alcohols, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with strong acids or polar solvents.

Typical settings include automotive, general industrial maintenance, and hydraulic and pneumatic systems.
