568-326 BUNA 70 SQUARE CUT RINGS

SH70326 is an AS568-326 black Buna-N (Nitrile) 70 Shore A square profile Quad-Ring built to an inside diameter of 1.6 in (40.64 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.02 in (51.31 mm). In service, this quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

The material holds up against water, greases and lubricants, and many alcohols. Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with strong acids or ozone and direct sunlight.

Typical settings include construction equipment, agricultural equipment, and automotive.

SH70326 ships individually. Unit weight is approximately 4.7773 g and nominal inside diameter is listed as 1 5/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
