Festo
186278
Push-in fitting, rotatable QSR-G1/4-6
The Festo part number 186278 is a standard straight industrial component featuring a 3.4 mm nominal width, 17.2 mm tubing insertion depth, and a push-pull structural design with a sealing ring on the screwed plug. Operating on compressed air according to ISO 8573-1:2010 [7:-:-], it supports lubricated operation, handles temperatures from 0 °C to 60 °C, and maintains an operating pressure ranging from -0.095 MPa to 0.6 MPa across the full temperature range or up to 1.4 MPa depending on temperature. The unit weighs 25 g, requires a nominal tightening torque of 9 Nm with a ±20% tolerance, and achieves a maximum rotational speed of 500 rpm with a 0.012 Nm max. radial torque.
