.562" C/S (9/16") (14.27 MM)

This o-ring cord stock is supplied in black Buna-N (Nitrile) 70 Shore A measuring a cross section of 0.562 in (14.27 mm), catalogued under part number 0284562. It eliminates long lead times on large-diameter custom rings.

It resists propane and butane, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) delivers low compression set under sustained load and the most widely specified general-purpose sealing elastomer.

Common environments for this compound include construction equipment, fluid power, and hydraulic and pneumatic systems.

Order part number 0284562, sold by the foot. Check the compound against your process media, pressure and temperature before committing to a design.
