I'm using them in the garage on copper pipe which is carrying old engine oil. No leaks yet (been in about 6-8 months) but there is very little pressure involved.Quote:

The name of the tool escapes my memory(seniors disease:(),they have only been on the market for a couple of years.
We have used them on chilled water pipes as well.
Yep i think that is it,does up to 32mm.Quote:
