Part number H1.9X11 is a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 11 mm (0.433 in), a cross section of 1.9 mm (0.075 in), and an outside diameter of 14.8 mm (0.58 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The material holds up against propane and butane, many alcohols, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.
It sees regular use in construction equipment, automotive, and fluid power.
