Ordered as H90M1X16, this is a black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 16 mm (0.63 in), a cross section of 1 mm (0.039 in), and an outside diameter of 18 mm (0.71 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to many alcohols, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) offers reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with strong acids or automotive brake fluid.
Maintenance and OEM teams specify it across agricultural equipment, fluid power, and hydraulic and pneumatic systems.
Stocked as H90M1X16 and sold individually. Unit weight is approximately 0.058 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
