2.5MM CS X 13MM ID BLACK BUNA 90D

This o-ring is supplied in black Buna-N (Nitrile) 90 Shore A built to an inside diameter of 13 mm (0.512 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 18 mm (0.71 in), catalogued under part number H90M2.5X13. It compresses into its gland to block fluid or gas migration across a joint.

As a material, Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs and low compression set under sustained load. The compound resists hydraulic fluids, many alcohols, and propane and butane. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or automotive brake fluid are present.

Maintenance and OEM teams specify it across hydraulic and pneumatic systems, construction equipment, and fluid power.

H90M2.5X13 ships individually. Unit weight is approximately 0.318 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
