This o-ring is supplied in black Buna-N (Nitrile) 90 Shore A with an inside diameter of 110 mm (4.331 in), a cross section of 5 mm (0.197 in), and an outside diameter of 120 mm (4.72 in), catalogued under part number H90M5X110. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
This material stands up to water, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving ketones or ozone and direct sunlight call for a different compound.
Common environments for this compound include fluid power, construction equipment, and hydraulic and pneumatic systems.
This item is sold individually under part number H90M5X110. Unit weight is approximately 10.036 g. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
