Product Specification

-
H90M2X50 is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 50 mm (1.969 in), a cross section of 2 mm (0.079 in), and an outside diameter of 54 mm (2.13 in). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, strong abrasion and tear resistance. The compound resists hydraulic fluids, water, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or automotive brake fluid will shorten service life.

You will find this material specified across fluid power, automotive, and agricultural equipment.
