APG stocks the H4X64, a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 64 mm (2.52 in), a cross section of 4 mm (0.157 in), and an outside diameter of 72 mm (2.83 in). An 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 and low compression set under sustained load. This material stands up to many alcohols, greases and lubricants, and hydraulic fluids. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in automotive brake fluid or ketones.
Typical settings include agricultural equipment, construction equipment, and automotive.
H4X64 ships individually. Unit weight is approximately 3.35 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
