This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 13.5 mm (0.531 in), a cross section of 2 mm (0.079 in), and an outside diameter of 17.5 mm (0.69 in), catalogued under part number H2X13.5. It creates a positive seal at flange, piston and rod interfaces without added hardware.
This material stands up to hydraulic fluids, petroleum-based oils, and water. That behavior comes from the compound itself: Buna-N (Nitrile) delivers low compression set under sustained load, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving ozone and direct sunlight or polar solvents call for a different compound.
Common environments for this compound include construction equipment, general industrial maintenance, and fluid power.
H2X13.5 ships individually. Unit weight is approximately 0.1923 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
