Festo
7842
Quick connector ACK-1/8-PK-6
The Festo part number 7842 is an industrial component featuring a straight design with a 5.3 mm nominal width, an internal thread G1/8 pneumatic connection 1, and a pneumatic connection 2 for an 8 mm outside diameter tubing or 6 mm inside diameter barbed fitting with a nut. Constructed with an anodized wrought aluminum alloy union nut and screwed plug alongside PA-reinforced and TPE-U(PU) sealing rings, this component operates within a pressure range of -0.095 MPa to 1 MPa and an ambient temperature range of -10 °C to 60 °C using compressed air or liquid water. It offers a nominal tightening torque of 3.5 Nm with a ±20% tolerance, a moderate corrosion resistance class of CRC 2, and comes in a pack size of 10.
