APG stocks the H90M1.6X6.1, a black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 6.1 mm (0.24 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 9.3 mm (0.37 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
This material stands up to greases and lubricants, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in polar solvents or automotive brake fluid.
You will find this material specified across fluid power, general industrial maintenance, and construction equipment.
Stocked as H90M1.6X6.1 and sold individually. Unit weight is approximately 0.0676 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
