Festo
531680
Quick coupling plug KS4-1/2-I
The Festo industrial component, part number 531680, features a nominal width of 7.85 mm and an internal thread G1/2 pneumatic connection 1, constructed from nickel-plated brass with RoHS compliance and a product weight of 57 g. It operates across a pressure range of -0.095 MPa to 1.2 MPa (-0.95 bar to 12 bar / -13.775 psi to 174 psi) in ambient temperatures from -10 °C to 60 °C, delivering a normal nominal flow rate of 756 l/min to 1314 l/min (normalized to DIN 1343) and 819.5 l/min to 1424.4 l/min (standardized to ISO 8778) using compressed air as per ISO 8573-1:2010 [7:-:-] with optional lubricated operation. The unit requires a nominal tightening torque of 32.5 Nm with a ±20% tolerance, and achieves a corrosion resistance class (CRC) of 1 with VDMA24364-B1/B2-L LABS conformity.
