Having just put a couple of crimps on with a pair just like the latter -
they need a bit of welly on the squeeze, but the crimp didn't want to
come off. What's the problem with them?

They don't put sufficient overall "size" pressure on the crimp ..

And because you never know whether the pressure applied on a non ratchet
tool has been enough to complete a proper joint. If not then you don't
get a gas tight joint and don't find out until it goes high resistance
later (thro' looseness or corrosion) and the joint or the loop overheats.


"a gas tight joint". Interesting. That phrase is used in the blurb for
Wago connectors as well.

It clearly communicates the meaning, but how did 'gas tight' become
applied to electrical connections?
