3.5MM CS X 92MM ID BLACK BUNA 70D

APG stocks the H3.5X92, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 92 mm (3.622 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 99 mm (3.9 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to petroleum-based oils, propane and butane, and hydraulic fluids. Buna-N (Nitrile) is specified for low compression set under sustained load 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 polar solvents or strong acids.

Maintenance and OEM teams specify it across general industrial maintenance, automotive, and agricultural equipment.

H3.5X92 ships individually. Unit weight is approximately 3.525 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
