Part number H50465 is an AS568-465 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 17.955 in (456.06 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.505 in (470.03 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 low compression set under sustained load. The material holds up against many alcohols, hydraulic fluids, and greases and lubricants. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where automotive brake fluid or polar solvents are present.
You will find this material specified across fluid power, general industrial maintenance, and construction equipment.
H50465 ships individually. Nominal inside diameter is listed as 18 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
