This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A measuring an inside diameter of 17 mm (0.669 in), a cross section of 1.2 mm (0.047 in), and an outside diameter of 19.4 mm (0.76 in), catalogued under part number H1.2X17. It remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to hydraulic fluids, greases and lubricants, and water. Buna-N (Nitrile) offers strong abrasion and tear resistance, low compression set under sustained load. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or polar solvents are present.
Maintenance and OEM teams specify it across construction equipment, fluid power, and agricultural equipment.
Stocked as H1.2X17 and sold individually. Unit weight is approximately 0.0001 g. Review your operating media and conditions against this specification before installation.
