Q-117 BUNA 70 Q RING

QH70117 is an AS568-117 black Buna-N (Nitrile) 70 Shore A quad profile Quad-Ring measuring an inside diameter of 0.799 in (20.29 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.005 in (25.53 mm). In service, this quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

Expect good resistance to petroleum-based oils, water, and propane and butane. Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. 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 strong acids are present.

It sees regular use in agricultural equipment, construction equipment, and fluid power.
