-394 BLACK BUNA 50D O-RING

Part number H50394 is an AS568-394 black Buna-N (Nitrile) 50 Shore A O-Ring with an inside diameter of 24.94 in (633.48 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 25.36 in (644.14 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to propane and butane, greases and lubricants, and water. Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ketones or strong acids will shorten service life.

Common environments for this compound include hydraulic and pneumatic systems, agricultural equipment, and automotive.

This item is sold individually under part number H50394. Nominal inside diameter is listed as 25 inch. Check the compound against your process media, pressure and temperature before committing to a design.
