Part number H2.4X18.3 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 18.3 mm (0.72 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 23.1 mm (0.91 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
As a material, Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and low compression set under sustained load. Expect good resistance to greases and lubricants, hydraulic fluids, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or strong acids are present.
Maintenance and OEM teams specify it across construction equipment, fluid power, and hydraulic and pneumatic systems.
H2.4X18.3 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
