5.7MM CS X 59.6MM ID BLACK BUNA 90D

H90M5.7X59.6 is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 59.6 mm (2.346 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 71 mm (2.8 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Supplementary detail from the product record: Metric O-RING, JIS P60.

It resists many alcohols, water, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or strong acids will shorten service life.

Common environments for this compound include fluid power, hydraulic and pneumatic systems, and general industrial maintenance.

H90M5.7X59.6 ships individually. Unit weight is approximately 7.208 g. Check the compound against your process media, pressure and temperature before committing to a design.
