APG stocks the H1.5X49, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 49 mm (1.929 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 52 mm (2.05 in). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
As a material, Buna-N (Nitrile) offers reliable performance in both static and dynamic service, low compression set under sustained load. It resists hydraulic fluids, many alcohols, and petroleum-based oils. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or ozone and direct sunlight will shorten service life.
It sees regular use in fluid power, hydraulic and pneumatic systems, and agricultural equipment.
Order part number H1.5X49, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
