Product Specification

-
Ordered as H90M5.7X229.3, this is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 229.3 mm (9.028 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 240.7 mm (9.48 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. This item is further identified as Metric O-RING, JIS G230.

Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, strong abrasion and tear resistance. The material holds up against greases and lubricants, many alcohols, and hydraulic fluids. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to strong acids or ketones will shorten service life.

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