Product Specification

-
The H2.5X23.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 23.5 mm (0.925 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 28.5 mm (1.12 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Buna-N (Nitrile) delivers low compression set under sustained load and the most widely specified general-purpose sealing elastomer. The material holds up against many alcohols, petroleum-based oils, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

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