Product Specification

-
APG stocks the H50025, an AS568-025 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 1.176 in (29.87 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.316 in (33.43 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to hydraulic fluids, greases and lubricants, and petroleum-based oils. Buna-N (Nitrile) is specified for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It should not be specified for service in ketones or polar solvents.

Common environments for this compound include agricultural equipment, general industrial maintenance, and construction equipment.

H50025 ships individually. Nominal inside diameter is listed as 1 3/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
