2.5MM CS X 18.5MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 18.5 mm (0.728 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 23.5 mm (0.93 in), catalogued under part number H2.5X18.5. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, strong abrasion and tear resistance. It resists water, hydraulic fluids, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or polar solvents will shorten service life.

Common environments for this compound include hydraulic and pneumatic systems, fluid power, and construction equipment.

Order part number H2.5X18.5, sold individually. Unit weight is approximately 0.405 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
