Dixon QM44WF 1/2 in Body 3/4 in ID Hose N-Series Dix-Lock Coupling

The Dixon Valve QM44WF is a new N-Series Dix-Lock pneumatic quick-disconnect plug (coupler half) with a 1/2 in. body, constructed from plated steel for corrosion resistance in industrial air-line service. The part number decodes as follows: "QM" = N-Series Dix-Lock style (ball-lock, sleeve-operated), "44" = 1/2 in. body size (both body and hose end are Size 4 = 1/2 in.), and "WF" = Whip-Fit / ferrule end designed to accept and secure a 3/4 in. inner-diameter air hose without a separate hose barb, using the integral swaged ferrule and knurled locking nut visible in the photos. The integrated safety locking sleeve, clearly visible as the double-knurled collar in the images, prevents accidental disconnection under live pressure by requiring the sleeve to be manually retracted before the plug can be separated from a mating N-Series socket. This plug mates with Dixon N-Series (Dix-Lock) sockets and is compatible with Milton, Hansen, and other N-style quick-disconnect bodies; typical applications include shop air distribution, pneumatic tool lines, and portable compressor hose assemblies operating at pressures up to 300 PSI.
