Great value crimp connectors

I’ve started using the heat shrink crimps, fairly cheap online and just can’t see past them now. Wish I had found out about them years ago!

Heat shrink + Water tight, all I ever use now. As they shrink the adhesive gets squeezed out the ends. Double whammy of an extra strong crimp as well as being completely water tight. If I'm not soldering, its those badboys that go on now.

Crimps as usual, but the normal hard plastic is heatshrink with glue inside it which runs out the end when heated, keeps them water proof, and improves the strength massively

I can give you 30 years of field experience as a Telecommunications Network Engineer and tell you it doesn't.
We used heatshrink closures for decades and, unless one had been put on pretty brilliantly, they tended to allow water in, retain the water and cause corrosion on pairs, often with catastrophic results to cable joints.
I'm not suggesting that you abandon these heatshrink closures but what I am saying is do not assume that you can fit one in a position where it will be subject to regular contact with water, whether that be water traps or water kicked up fronm the road etc.
They really need to be fitted to wiring that will have very little to no possibility of contact with water.

They will certainly look neater and smarter.
Crimps are less likely to retain water and can be disconnected and cleaned up, generally.
I have not really seen these new heatshrink closures but, I assume, you are advised to abrade the cable around it's circumference and not longtitudinally, basically, the glue should have something to grip to.
I would use heatshrinks, I would just not use them in areas that they are prone to have more than their fair share of water contact.

I love toolstation, just so bloomin handy, and the automotive stuff like brake cleaner and other odds and sods is not to bad either!

First off I am an Electrician so this m ight explain the following.

Problem with them is they are a very low temperature solder, basically a metal glue.
This is because the solder has to melt at a temperature just below the temperature the heat shrink shrinks giving a low temp join.

A mechanic mate swore by these for a week, then went back to crimps.
Personally I always try use Utilux brass crimps with a proper crimping tool or solder lugs with a decent soldering iron.
I have never trusted the squeeze crimps with the plastic covers that get squeezed with it unless they are crimped with a proper ratchet crimper that does the wire and insulation as one. I have seen far to many of these type crimped with the cheap single crimp tools or horror of horrors side cutters.

Why did he go back to crimps
