568-116 BUNA 70 SQUARE CUT RINGS

SH70116 is an AS568-116 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring built to an inside diameter of 0.737 in (18.72 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.943 in (23.95 mm). In service, this quad-ring provides a dual sealing band on each contact face for improved reliability.

It resists greases and lubricants, water, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving strong acids or polar solvents call for a different compound.

Typical settings include fluid power, general industrial maintenance, and automotive.

Reference part number SH70116 when ordering; the item is sold individually. Unit weight is approximately 0.5237 g and nominal inside diameter is listed as 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
