Product Specification

-
Part number H70MD329 is an AS568-329 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 1.975 in (50.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.395 in (60.83 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 propane and butane, water, and greases and lubricants. Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or automotive brake fluid call for a different compound.

This o-ring is metal detectable for HACCP and foreign-body control programs. You will find this material specified across agricultural equipment, construction equipment, and fluid power.

This item is sold individually under part number H70MD329. Nominal inside diameter is listed as 2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
