Part number H3X88 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 88 mm (3.465 in), a cross section of 3 mm (0.118 in), and an outside diameter of 94 mm (3.7 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, Buna-N (Nitrile) offers reliable performance in both static and dynamic service, low compression set under sustained load. The material holds up against hydraulic fluids, propane and butane, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life.
Common environments for this compound include general industrial maintenance, agricultural equipment, and construction equipment.
H3X88 ships individually. Unit weight is approximately 0.0025 g. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
