3MM CS X 44.5MM ID BLACK BUNA 70D

APG stocks the H3X44.5, a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 44.5 mm (1.752 in), a cross section of 3 mm (0.118 in), and an outside diameter of 50.5 mm (1.99 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Expect good resistance to many alcohols, hydraulic fluids, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or polar solvents will shorten service life.

You will find this material specified across automotive, agricultural equipment, and fluid power.

Order part number H3X44.5, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
