568-214 BUNA 70 SQUARE CUT RINGS

Part number SH70214 is an AS568-214 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring measuring an inside diameter of 0.984 in (24.99 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.262 in (32.05 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. It resists water, many alcohols, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or strong acids call for a different compound.

You will find this material specified across construction equipment, fluid power, and general industrial maintenance.

SH70214 ships individually. Unit weight is approximately 1.288 g and nominal inside diameter is listed as 1 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
