The H8.4X179.1 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 179.1 mm (7.051 in), a cross section of 8.4 mm (0.331 in), and an outside diameter of 195.9 mm (7.71 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. This material stands up to many alcohols, petroleum-based oils, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where polar solvents or strong acids are present.
Common environments for this compound include hydraulic and pneumatic systems, automotive, and general industrial maintenance.
