Festo
177685
Push-in fitting CQ-1/2-18
The Festo part number 177685 is a 24 g industrial component featuring a nominal width of 12.7 mm, an external thread G1/2 pneumatic connection 1, and a pneumatic connection 2 for an 18 mm outside diameter piping system or pneumatic tubing. Constructed with a POM housing and a sealing ring on the screwed plug, this push-pull structural design operates within a -25 °C to 70 °C ambient temperature range using compressed air as per ISO 8573-1:2010 [7:-:-]. It offers an operating pressure of -0.95 bar to 7 bar across the entire temperature range, a temperature-dependent operating pressure of -0.95 bar to 15 bar, a nominal tightening torque of 2.5 Nm with a ±10% tolerance, and moderate corrosion resistance class 2.
