Hi guys.

I normally only work on domestic stuff so all my tools are obviously geared to that.
My question is what sort of tools do you guys use for working with 54mm compression fittings? And copper threads?
Thanks.
 
Don't normally use compression on 54 mm but Stilsons 24-36" anything bigger compression wise is different and has bolts instead of one nut (like a flange)

but it press or soldered normally

But most is like domestic but bigger

You can hire threading machines from bss etc have a look on the rems site

Sorry mate.

What I meant was. On a domestic valve you'd just use your adjustable and grips. Where's as the ISO valves I'll be using on site are used with a male copper thread both sides.

. As there 54mm would you still use stilsons on the copper? Just worried they may round them off a bit.
 
Hmm. I'll have to check what paste we're using on the job just to be sure, but yes it is hot and cold.
 
Is the copper thread liable to cross if tightened to much? I'm just thinking that copper is quite soft

If in doubt about cross threading, unwind the connection until you hear a click then start to tighten again. Damaged to fittings can occur if the male bottoms out and you continue to over tighten.

Ridgid E110 wrench has many uses besides water pumps. Offset allows jaws to deepen as they widen. Best online price £39.00 with free delivery.
 
Thanks for the advice all. Personally I don't feel with a set of 10/12inch adjustables I can tighten that size fitting properly unless using a bar on the handle.
The job I'm on are moaning about the marks the stilsons leave on the fittings even though non of it is in show.

how many 35mm+ comp fittings do you have? Normally if we have to put say a lever valve on 35mm tube we would get 35mm to 1 1/4" end feed or press irons and use a screwed valve, bit more secure than compression, obviously has the disadvantage of being harder to take off depending on location but its easier to wind it on rather than doing up comp nuts.

Quite a few to be fair mate. 35/42/54 and lots of. We are using male irons on live side but compression the other.
