Product Specification

-
Part number H90M6X70 is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 70 mm (2.756 in), a cross section of 6 mm (0.236 in), and an outside diameter of 82 mm (3.23 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, most widely specified general-purpose sealing elastomer. The compound resists hydraulic fluids, many alcohols, and greases and lubricants. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ozone and direct sunlight or automotive brake fluid will shorten service life.

Typical settings include agricultural equipment, general industrial maintenance, and construction equipment.

Reference part number H90M6X70 when ordering; the item is sold individually. Unit weight is approximately 8.853 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
