Description
Tube nuts sit on the line they seal, so a closed ring cannot drop over them. The Snap-on QJRXSM14A flare nut head handles that problem at 14 mm. It wraps the nut on six flats, yet leaves a gap for the tube. Then it locks into a J-shank torque wrench body.

Jobs for the QJRXSM14A
Metric tube fittings show up all over a plant. For instance, you will find them on machine-tool coolant lines, gauge lines and small hydraulic circuits. They also appear on compressor and dryer piping. In each case, the fitting needs a set torque, while the narrow tube leaves little room to work.
Matching the Snap-on QJRXSM14A flare nut head to a body
Snap-on makes this size in J shank only, with no Y version at 14 mm. On SMK Vietnam, J-shank choices include the QD2IN50A, whose 10-50 N·m scale sits fully inside the head rating. The QD2IN100A reaches 100 N·m, so keep it at 81 N·m or less with this head. Electronic options include the CTECH1J240A and CTECHL1J240A. Because the head keeps the 2.50 in J spacing, the QD bodies need no adjustment math.
QJRXSM14A versus neighbor sizes
Measure the nut across the flats before you order. Snap-on lists the 13 mm QJRXSM13A at 58 ft-lb and the 15 mm QJRXSM15A at 60 ft-lb. If a 15 mm joint needs more, the Y-shank QYRXSM15A carries 71 ft-lb.
Keeping the QJRXSM14A in shape
Look at the jaw tips before each job, since a spread or chipped tip can mark a nut. Also keep the slot clean of sealant and grit. Then store the head in a labeled tray next to the body. Finally, send the body for periodic recalibration, as Snap-on recommends.
