4MM CS X 52MM ID BLACK BUNA 70D

H4X52 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 52 mm (2.047 in), a cross section of 4 mm (0.157 in), and an outside diameter of 60 mm (2.36 in). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to many alcohols, propane and butane, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) delivers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to ketones or strong acids will shorten service life.

Common environments for this compound include construction equipment, agricultural equipment, and general industrial maintenance.
