The H50044 is an AS568-044 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 3.739 in (94.97 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.879 in (98.53 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
It resists propane and butane, many alcohols, and water. That behavior comes from the compound itself: Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or ozone and direct sunlight are present.
Typical settings include agricultural equipment, construction equipment, and automotive.
Order part number H50044, sold individually. Nominal inside diameter is listed as 3 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
