-105 BLACK BUNA 70D O-RING

This o-ring is supplied in AS568-105 black Buna-N (Nitrile) 70 Shore A measuring an inside diameter of 0.143 in (3.63 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.349 in (8.86 mm), catalogued under part number H70105. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to greases and lubricants, water, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, strong abrasion and tear resistance. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with automotive brake fluid or ozone and direct sunlight.

Typical settings include hydraulic and pneumatic systems, general industrial maintenance, and agricultural equipment.

H70105 ships individually. Unit weight is approximately 0.1316 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
