-323 BLACK BUNA 70D O-RING

H70323 is an AS568-323 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 1.287 in (32.69 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.707 in (43.36 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to hydraulic fluids, propane and butane, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, 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 ozone and direct sunlight or ketones.

Typical settings include automotive, agricultural equipment, and construction equipment.

H70323 ships individually. Unit weight is approximately 3.33 g and nominal inside diameter is listed as 1 5/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
