Description
Tube fittings often use soft brass or thin steel nuts, which round off easily under a 12-point grip. The Snap-on QYRXS32A flare nut head holds a 1 in nut on all six flats instead. It then locks onto a Y-shank torque wrench body, so the fitting reaches its set value without damage to the corners.

6-point or 12-point?
Snap-on also lists a 12-point QYRX32A in the same 1 in size and rating. A 12-point head is easier to place in a tight swing arc. However, the 6-point QYRXS32A spreads force over the full face of each flat. That makes it the safer pick for soft or worn tube nuts.
Which bodies suit the QYRXS32A?
It needs a Y-shank body. On SMK Vietnam, that includes the QD3IN200B, whose scale tops out at 140 ft-lb, well inside the head rating. It also includes the QC3P150 and QC3P200 preset bodies and the CTECH2Y100A electronic wrench. With the QC3P200, though, keep the preset at 158 ft-lb or below. Because the head keeps the standard 3.00 in Y spacing, the dual-range QD bodies need no adjustment calculation.
Typical QYRXS32A jobs
- Hydraulic tube nuts on presses and mobile equipment.
- Refrigerant and compressed air fittings on plant services.
- Fuel and lube lines on generators and engines.
For smaller lines, Snap-on also makes the QJRXS32A in J shank, rated at 60 ft-lb.
Care and storage for the QYRXS32A
Check the jaw faces for burrs before each job, since a burr can mark a soft nut. Then keep the head in a dry tray with its siblings. Also keep the body on its calibration schedule, as Snap-on advises.
