Press fit purchase, possibly rothenberger

It is only when the fittings setup allows good leverage meaning it is easier to twist, the machine is fine, just wandering if i do twist, will this destroy the tightness of the fitting? Might pressure test it to find out!

It won't do anything to the pressure. Someone on here pressure tested the fittings to 5bar crimped only without the o ring I remember from a previous post. None of my fittings have ever rotated after pressing, but I have came across rotating fittings in older installations that have been installed for some time and they are absolutely fine.

I have the Geberit machine and technically, the jaws have to be calibrated annually. Maybe this could be something to do with the rotation problem.

I have hand crimping tools from Buteline and then have a crimp guage and the ability to adjust the jaw clamps.

I really like the simplicity of pressing fittings and on a job today surrounded by expensive timber, it saved a headache in trying to solder, plus it's much quicker.
Downside is that it's often difficult to get the gun into tight spaces and fittings have to be carefully planned out.
I like using non rotating XPress fittings alongside Copper Tectite Sprint fittings which are copper pushfits and can allow the pipe to rotate in the fitting. This often makes it easier to get the Akku Press in for the XPress fittings.
The biggest bonus is just how neat and thoroughly good looking a towel radiator install is when using XPress chrome fittings, plus the chrome fittings press directly on to chrome pipe without the need for scribing or filing.
It's very rare now that I have to solder and much prefer XPress and Tectite for speed, simplicity and neatness. They're much neater than those big ugly white plastic pushfits, but I'll use these too if the situation on the job calls for it.
My next investment is a much lighter and more compact press gun than the very heavy and bulky Akku Press.

1. Yes specific fittings for each
2. M jaws work on mapress, sanha and xpress take a look at Pipework Systems | Pipes | Fitting | Valves | Pipekit and use their live chat. Their people are experts on what works with what.
3. Shop around mate. I got mine second hand but is mint apart from a bit of dust
4. Depends where you are mate, some places stick them all the time. Maybe phone round. I usually have to overnight mine using the people above.
5.cant help you line is novopress
6. Mine was about £110 inc vat and 4 jaws

FYI All second hand press tools need calibrating
