Product Specification

-
APG stocks the H2.4X30.3, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 30.3 mm (1.193 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 35.1 mm (1.38 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. It resists hydraulic fluids, propane and butane, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It is not the right choice where automotive brake fluid or strong acids are present.

It sees regular use in construction equipment, agricultural equipment, and hydraulic and pneumatic systems.

Stocked as H2.4X30.3 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
