APG stocks the HQ4136, an AS568-136 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring measuring an inside diameter of 1.987 in (50.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.193 in (55.7 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

Maintenance and OEM teams specify it across construction equipment, general industrial maintenance, and agricultural equipment.

Order part number HQ4136, sold individually. Nominal inside diameter is listed as 2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
