Yes, the SPIN Tools do not alter significantly the thickness of the tube wall so as long as the tubing has the standard specifications for high pressure fluids, nothing changes. Please refer to this question for more details on tube wall thickness.

Yes.

No.

In HVAC, it’s not usual to make flares in hard copper, so the flaring SPIN tool wasn’t designed to make them on hard copper.

Yes.

1) Precision: the flares will always have the same size and will fit perfectly; the swages present a perfect depth and a tight fitting, that will make the brazing easier and will reduce the fatigue stress over the coupling area; 2) Quality: the flare/swage will keep its malleability, which will ensure better couplings overall; the
