Ferrule clamping

I've had a pair of these CK crimpers for around 8 years,
They'll do all sizes upto 16 mm and I think with nothing to go wrong or break on them they'll last a very long time
Cost around £23 if you're sensible and shop around

They look good but how do you know if you've applied the correct force to secure without over tightening?

Had to do some 50 mm ferrules last week which was a first for me
I don't have a crimping tool for 50mm ferrules !

So I used a Cimco hexagonal crimper (meant for lugs) which on 50 mm didn't really touch them and then I realised that of course the tube was much thinner than a copper tube lug so I tried 35 mm which worked really well, crimped in two places as the crimping area is quite narrow

As it's been used on a generator to machine setup I've had to disconnect and reconnect every day so I've checked them over every time and they seem to be fine .

By using a bit of common sense and practical skill.

Plus the ferrule will always deform further when the terminal it goes into is tightened

ive been using these for a couple years and havent had any issues, crimped 0.25 to 6mm with them (they crimp upto 16mm)

They work on the principle that when you've closed them fully that's it, they're crimped!

If you don't crimp them enough they can be easily pulled off

I like these as they're simplistic reliable and also I've never had anyone pull the ferrule off which can be an issue with the square indent type,

I've lost count of how many I've had to redo at work, most blokes have the square type or weidmullers which are actually pretty good too and it's always the square ones that come off

That's the exact pair I have, I prefer the comfortable grips on those to the skinny plastic grips with my arthritic hands

The ratchet crimper I use puts 4 to 5 round indents into the ferrule.

I do have a pair of Knipex long nose pliers which can be used for stripping small cables and crimping small ferrules.

These look pretty decent to, however they only do a small number of ferrule sizes

Weidmuller every time for me.
I carry a PZ4, PZ6 Roto, PZ16 & PZ50 on the van, use them on most jobs.
Expensive, but, they last years if not abused, I've only gone through one pair of PZ's in 20+ years, and that was due to crimping over sized lugs with them, trying to save time.

They look pretty rubbish to me, multi-tools like that are rarely very good at any of the functions that claim to do.

The jaws of the pliers part are far too far away from the hinge to really be a useful pair of pliers for a start.

I've a pair of those knipex and I don't use them for ferrules, I've tried them and they do work however, it isn't too difficult to pull the ferrules off so I'd say ok in a pinch but I certainly wouldn't use them if I've got the proper ones on me

I use the RS ferrule crimpers when panel building but I have recently got a set of the knipex installation pliers brilliant bit of kit.

When you say "proper ones" do you mean the ratchet type?
