Product Specification

-
Part number H90M3X59.5 is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 59.5 mm (2.343 in), a cross section of 3 mm (0.118 in), and an outside diameter of 65.5 mm (2.58 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The compound resists petroleum-based oils, many alcohols, and hydraulic fluids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C).

It sees regular use in fluid power, construction equipment, and automotive.

H90M3X59.5 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to 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.
