-316 BLACK BUNA 50D O-RING

Part number H50316 is an AS568-316 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 0.85 in (21.59 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.27 in (32.26 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs and most widely specified general-purpose sealing elastomer. It resists hydraulic fluids, many alcohols, and water. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to automotive brake fluid or strong acids will shorten service life.

Common environments for this compound include hydraulic and pneumatic systems, automotive, and general industrial maintenance.
