-112 BLACK BUNA 70D O-RING

APG stocks the H70112, an AS568-112 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 0.487 in (12.37 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.693 in (17.6 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to many alcohols, water, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ozone and direct sunlight or polar solvents.

Maintenance and OEM teams specify it across automotive, hydraulic and pneumatic systems, and general industrial maintenance.

Stocked as H70112 and sold individually. Unit weight is approximately 0.3104 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.
