Festo
3711
Quick connector ACK-3/8-PK-6
The Festo part number 3711 is a straight industrial component featuring a 5.3 mm nominal width, a G3/8 internal thread for pneumatic connection 1, and a connection for an 8 mm outside diameter pneumatic tubing or 6 mm inside diameter barbed fitting with a nut for pneumatic connection 2. Constructed with a wrought aluminum alloy anodized union nut and screwed plug alongside PA-reinforced and TPE-U(PU) sealing rings, this unit operates within a pressure range of -0.095 MPa to 1 MPa for compressed air and up to 0.6 MPa at 50 °C for water, across an ambient temperature range of -10 °C to 60 °C. Rated at a nominal tightening torque of 12.5 Nm with a ±20% tolerance, the assembly provides a CRC 2 moderate corrosion resistance class and accommodates any mounting position in packs of 10.
