Q-145 BUNA 70 Q RING

APG stocks the QH70145, an AS568-145 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring with an inside diameter of 2.55 in (64.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.756 in (70 mm). A quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Expect good resistance to hydraulic fluids, greases and lubricants, and petroleum-based oils. Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or ozone and direct sunlight will shorten service life.

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

Stocked as QH70145 and sold individually. Unit weight is approximately 1.3594 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
