I have purchased several makes and in all case cables slip out. I still have some Old ones left and they seem much harder to co (more material) than the skanky new ones. Latest used from CEF: https://www.cef.co.uk/catalogue/products/695628

I am using a ratchet crimper that works fine with mu old ones.

Running low now, help really appreciated.

Thanks

I buy them from various sources near wherever I may be working including CEF at times and never had a problem with any make (Only perhaps where the conductor slips out the moment you compress!!!).
So cant really suggest anything else as all seem to be ok to me whatever make!

the qualityof the crimping tool makes a big difference. also these crimps are not as good on soloid strand as they are on 7 strand cable. i use a knipex ratchet tool, adjustable pressure, narrow jaws so you can crimp each end separately. cost about £65 though.

I'm not the biggest fan of insulated crimpable terminals but on the odd occasion I buy them try to stick to the Hellermanntyton terminals. I have noticed that the cheaper no-name terminals tend to have thinner or softer insulation so this could have an effect how well they crimp.

Personally I rarely would use them for wire-wire joints, I find they are most often for earth ring tags and occasionally for the push-on (car electrics) style of terminals on equipment switches, etc.

Most insulated through-crimps are simply not suitable for solid conductors. The conductor does not deform enough to engage properly into the texture of the crimp barrel, instead the barrel tends to crush around the outside of the conductor without really gripping it. Proper crimps for solid tend to be uninsulated and need indent or hexagon tooling to apply enough pressure to deform, which doesn't work through the nylon sleeve of a coloured crimp. If you are having repeated failure with stranded or fine-stranded conductors then start again with a known good tool and brand-name crimps that match.
