An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
It resists petroleum-based oils, water, and greases and lubricants. Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong acids or automotive brake fluid.
Common environments for this compound include hydraulic and pneumatic systems, general industrial maintenance, and automotive.
H4X192 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
