Description
On 1 in hydraulic tube, a -16 O-ring face seal nut commonly measures 1-5/8 in across the flats. Such nuts sit on pump outlets and main pressure lines, where no socket can pass the tube. The Snap-on QYRX52A flare nut head reaches them with a slotted 12-point ring on a Y shank (0.560 in). So a Y click or electronic body can bring the nut to a known value in place.
What the sources agree on for the QYRX52A
- Opening: 1-5/8 in, 12-point, slotted.
- Shank: Y (0.560 in).
- Pin to fastener center: 3.00 in, the QYRX standard.
Beyond those points, the sources split. CAT1500i and the partner listing give one torque limit and one outside diameter. The UK Torque Brochure, however, prints other values for both, and the depth figures differ too. Therefore we leave rating, width and depth out, and Lost in HCM confirms them for your QYRX52A order.
Picking a Y body to drive the Snap-on QYRX52A flare nut head
- QC3P200 preset, 40-200 ft-lb, for one repeated high value.
- QC3P150 preset, 30-150 ft-lb.
- QD3IN200B dual scale, 40-200 N·m, read directly at the 3.00 in spacing.
- CTECH2Y100A ControlTech, 5-100 ft-lb, for lighter joints with a stored record.
Large -16 joints often carry high specs. So compare three numbers before you set the wrench: the joint value, the body range and the confirmed head limit. Then always work to the lowest of the three.
Other Snap-on routes to a 1-5/8 in nut
Snap-on’s 6-point inch flare table stops at 1-1/8 in, so no 6-point ring exists at this size. Instead, the thin QYO52ARTH covers 1-5/8 in on a Y shank, and the QJO52ARTH does so on a J shank. Those jaws slip in from the side, yet they grip only two flats. As a result, the slotted QYRX52A stays the better tool for a final pull on a tube nut. In CAT1500i, the QYRX48A sits one step smaller at 1-1/2 in.
Care for the Snap-on QYRX52A flare nut head
A large slotted ring works hard at every click. So measure the slot gap when the head is new, and then compare it at each service. Also clean hydraulic oil off the shank and the receiver before you fit the Snap-on QYRX52A flare nut head. Finally, never use it to free a seized nut, as Snap-on warns.
QYRX52A pricing through our partner
Our partner Lost in HCM sources the QYRX52A and returns a written quote, while SMK Vietnam only lists it. Give the team your Y body, the fitting size and the joint value. After that, send the QYRX52A request through Lost in HCM. More sizes sit under torque wrench heads and adaptors, and you can also contact SMK Vietnam.
QYRX52A: face seal fit and limits
Will the QYRX52A fit a -16 face seal nut?
Usually, since that nut commonly has a 1-5/8 in hex. Measure the flats first, because fittings vary by maker.
Why does this page show no torque limit for the QYRX52A?
CAT1500i and the UK Torque Brochure disagree on that figure. So Lost in HCM confirms the right figure with the quote.
Can a J body run the QYRX52A?
No. It has a Y shank, so it needs a Y body such as the QC3P200.
