Festo
3712
Quick connector ACK-1/4-PK-6
The Festo part number 3712 is a straight industrial component featuring a 5.3 mm nominal width, a G1/4 internal thread pneumatic connection 1, and a connection 2 for 8 mm outside diameter pneumatic tubing or 6 mm inside diameter barbed fittings with a nut. Constructed with an anodized wrought aluminum alloy screwed plug and union nut complemented by a PA-reinforced and TPE-U(PU) sealing ring, this component operates across a temperature range of -10 °C to 60 °C and handles pressures from -0.95 bar to 10 bar for compressed air or up to 0.6 MPa at 50 °C for water. Supplied in a pack size of 10, the unit requires a nominal tightening torque of 11 Nm with a ±10% tolerance and meets CRC 2 moderate corrosion stress along with VDMA24364-B1/B2-L LABS conformity.
