It is hard steel, much harder than stainless, which clamps into a vise on your bench. Lots easier (mostly) than fighting two wrenches or (god-forbid) a wrench and a crescent wrench. You do the same 1 1/4 turns, but having it steady in the vise makes life a lot easier. Using the pre-swage tool means all the torque goes to making your seal and is not inadvertently distributed onto other components as the system is built. Make it up outside, break it loose and when everything is ready, just go put the bits together. Works great, lasts forever, and well worth the additional outlay of cash.VancePS: Swagelok sells their own bender. Very good ones.

Hi Vance,you are getting me confused now. Am no plumber.I thought all I did was stick the tube in the swagelok fitting & do itup 1&1/4 turns. Will take your advice on the bender.Alan----- Original Message -----From: vbra676539@aol.comSent: Monday, October 10, 2011 10:29 AMSubject: Re: [PSUBS-MAILIST] Snoopy updatesI hope you bought mandrels for the swage ends. The females (tube end with nut and ferrule) are infinitely easier to form in a vise, and virtually eliminate galling and cross threading, among other things. Worth the investment if you haven't. Trust me on that. And no hardware store benders and cutters either. Buy the best up front. You'll be happier later. Good luck, mate.

Timely advice Vance,Have just bought a heap of swagelok fittings (ouch expensive) & stainless tube.I'm using solenoid valves as well as a manually operated system for ballasts etc,so it's going to be looking like spaghetti.Alan----- Original Message -----From: vbra676539@aol.comSent: Monday, October 10, 2011 8:24 AMSubject: Re: [PSUBS-MAILIST] Snoopy updatesAlec,Don't know if you're onto this trick, but when you get ready to re-plumb the high pressure air (as mentioned in the caption of one of those photos), we used to bend a template set out of 1/8" aluminum tig rod before committing to the stainless (which is very unforgiving, especially in small pieces, as you have already discovered). You can get your lengths and angle changes right to a gnat's hair with the rod, and do it on the cheap. Go centerline to centerline of your fittings, cutting to the depth required for your Swagelok fit-up, but remember to add/subtract an additional 1/8" to the tubing for arcs in stainless. Try it with a chunk of copper tube, if you like, but doing it before you do it for real is a definite improvement over the sweating and grunting while sitting in the sub. You'll get exactly what you need in stainless without wasting the HP tubing in the process, and you can build the whole thing on the bench--and it will fit like the proverbial champ.Vance
