-234 BLACK BUNA 50D O-RING

APG stocks the H50234, an AS568-234 black Buna-N (Nitrile) 50 Shore A O-Ring with an inside diameter of 2.984 in (75.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.262 in (82.85 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to petroleum-based oils, many alcohols, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or ozone and direct sunlight call for a different compound.

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

Stocked as H50234 and sold individually. Nominal inside diameter is listed as 3 inch. Review your operating media and conditions against this specification before installation.
