3MM CS X 274MM ID BLACK BUNA 70D

H3X274 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 274 mm (10.787 in), a cross section of 3 mm (0.118 in), and an outside diameter of 280 mm (11.02 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) delivers strong abrasion and tear resistance, low compression set under sustained load. This material stands up to hydraulic fluids, propane and butane, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or ketones will shorten service life.

Typical settings include agricultural equipment, general industrial maintenance, and construction equipment.

H3X274 ships individually. Unit weight is approximately 7.482 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
