-219 BLACK BUNA 90D O-RING

H90219 is an AS568-219 black Buna-N (Nitrile) 90 Shore A O-Ring measuring an inside diameter of 1.296 in (32.92 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.574 in (39.98 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Expect good resistance to greases and lubricants, hydraulic fluids, and petroleum-based oils. 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 ketones call for a different compound.

You will find this material specified across hydraulic and pneumatic systems, construction equipment, and agricultural equipment.

H90219 ships individually. Unit weight is approximately 0.0015 g and nominal inside diameter is listed as 1 5/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
