Product Specification

-
The H3X26.2 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 26.2 mm (1.031 in), a cross section of 3 mm (0.118 in), and an outside diameter of 32.2 mm (1.27 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, low compression set under sustained load. Expect good resistance to water, propane and butane, and many alcohols. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where strong acids or polar solvents are present.

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