The H70924 is an AS568-924 black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 1.72 in (43.69 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 1.956 in (49.68 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
It resists hydraulic fluids, water, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) offers reliable performance in both static and dynamic service, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in ozone and direct sunlight or polar solvents.
It sees regular use in automotive, hydraulic and pneumatic systems, and general industrial maintenance.
H70924 ships individually. Unit weight is approximately 1.2998 g. 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.
