Looking for good quality yellow , red and blue Insulated through Crimps

[Let me think]

this is my beast. the adjstable pressure feature allows to crimp the yellow ones easily by first crimping at a lower pressure, then a higher one.

These are the dog undercarriage Now another tool I need to go and buy based on their looks. BTW when my good lady asks WTF are these for when they get delivered, @telectrix you'll be getting blamed for this latest purchase. ;P

Main problem with all these coloured crimps is they’re too big though.

Anyone got a link to any that actually fit!?

Only on Friday I connected 2.5 singles using red crimps. It’s a joke. How hard can it be to make them a snug fit.

SWA (brand, not armoured cable) are good quality.

This old chesnut again. It baffles me that they're one of about 3 connector types considered MF. Yes, a properly terminated crimp should be fine (although like other I have zero confidence in them on solid) - but how often do you find ones that aren't? Given the choice, then give me an old bakelite junction box under the floorboards than these any day. (Obviously Wagos are the superior option, but i'm hypothesizing).

To be fair I don’t recall ever finding a burnt out connection in a crimp, but many in old JB’s. Possibly to do with amounts of these joints in service though.

wow, that's what happens when you leave a set of mole grips and a crimping tool in your tool box and apply an exponential time field and some primordial goo - they evolve...

I can't say I've ever found any burned out in fairness - but none of the ones I've seen on site have ever filled me with confidence. One college I was at had its original RFC (serving 2x socket outlets in a corridor of 5 classrooms) broken and extended in each room to install dado some time in the early 2000's. The crimps had seated fine on the original 7/.029, but on the solid 2.5mm2 it was joined to, it just fell out with a light tug in many cases.
