Part number H90M3X24.2 is a black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 24.2 mm (0.953 in), a cross section of 3 mm (0.118 in), and an outside diameter of 30.2 mm (1.19 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.
It resists hydraulic fluids, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving ozone and direct sunlight or strong acids call for a different compound.
Common environments for this compound include fluid power, general industrial maintenance, and automotive.
H90M3X24.2 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
