2.5MM CS X 134MM ID BLACK BUNA 70D

APG stocks the H2.5X134, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 134 mm (5.276 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 139 mm (5.47 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists many alcohols, hydraulic fluids, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers low compression set under sustained load and an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or ketones call for a different compound.

It sees regular use in fluid power, general industrial maintenance, and hydraulic and pneumatic systems.

H2.5X134 ships individually. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
