Product Specification

-
APG stocks the H90M2.4X14.3, a black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 14.3 mm (0.563 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 19.1 mm (0.75 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to water, propane and butane, and many alcohols. Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with ketones or strong acids.

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

Stocked as H90M2.4X14.3 and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
