Q-130 BUNA 70 Q RING

Part number QH70130 is an AS568-130 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring with an inside diameter of 1.612 in (40.94 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.818 in (46.18 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

As a material, Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. The compound resists propane and butane, water, and hydraulic fluids. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or automotive brake fluid are present.

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

QH70130 ships individually. Unit weight is approximately 0.901 g. Review your operating media and conditions against this specification before 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.
