568-313 BUNA 70 SQUARE CUT RINGS

The SH70313 is an AS568-313 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring built to an inside diameter of 0.662 in (16.81 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.082 in (27.48 mm). This quad-ring delivers lower friction and better sealing stability than a comparable round-section o-ring.

Buna-N (Nitrile) is specified here for economical choice for high-volume maintenance programs, strong abrasion and tear resistance. This material stands up to water, greases and lubricants, and petroleum-based oils. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in strong acids or ozone and direct sunlight.

Common environments for this compound include agricultural equipment, automotive, and general industrial maintenance.

SH70313 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
