Product Specification

-
Ordered as H4X133, this is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 133 mm (5.236 in), a cross section of 4 mm (0.157 in), and an outside diameter of 141 mm (5.55 in). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, most widely specified general-purpose sealing elastomer. The compound resists hydraulic fluids, many alcohols, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or polar solvents will shorten service life.

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