Product Specification

-
H3.5X24 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 24 mm (0.945 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 31 mm (1.22 in). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. This material stands up to petroleum-based oils, water, and greases and lubricants. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with strong acids or ozone and direct sunlight.

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