CA-AB Heat shrink connector

[PeterT]

Has anyone used these? If I understand, they crimp like the regular ones but also heat activate the shrink & bond

Used them all the time at GM when I was there 15 years ago, was the recommended wire splice method, not sure if they still are with GM. Still use them a lot at the heavy truck shop now and see them a lot on highway transport stuff.

Yep, strip a bit from the end, crimp (use good quality crimpers), and use heat to shrink the insulator. There is a clear sealant that melts and seals the sleeve to the wire jacket. A heat gun is recommended for it but if you're careful with heat application then a micro-torch works just fine (what I usually use).

i use them quite often on automotive projects, the only caveat is that they say to use different crimp teeth, the ones for the hard plastic can and do sometimes cut the heat shrink around the crimp

I prefer uninsulated bare butt splices, then double wall heat shrink over top. If it’s in an outside environment. It’s a bit more work but it works fairly well

Same as the guys above, I use them often. Use the right crimper and they are great.

something i like to do with crimps, or soldered/heat shrunk connections that are going to be outside (trailer, deck wiring etc), splooge some dielectric grease in the crimp connector before crimping/heat shrink, or a soldered/heat shrink, splooge some more of that grease on the soldered connection, slide the heat shrink over and shrink

seems to help keep the road salt out for a little longer

I haven't used that particular brand of them but I think they are great. I've never really liked the simple crimp style but use them all the time anyhow. I think those melt sealant type are far superior for any location that MIGHT ever get wet.

Thanks. If I understand, this particular company makes 2 different crimps, one for regular/insulated & other for heat shrink. Or a mucho-deluxo with replaceble jaws.
I'm not committed to brand, just saw it on Amazon. Are there good crimper names to be aware of. I hate TRS (tool remorse syndrome) & buying them twice.

Ouch! Those crimpers are expensive. I don't doubt that they are very good quality and that they have interchangeable die/jaws with them is really nice, but holy cow the price.
On the other hand I have had Uber cheap ones that have come with a purchase of an assortment of fittings that were pure garbage. I eventually threw them away. I presently own 2 other sets also of low price, the cheapest are useable but are poor, the others are princess auto ones which would have been very moderate-low price and I don't mind them. I'd be willing to spend about half of what those ones you linked to costs, so I will probably never know what I'm missing.

I have used the heat shrink connectors on trucks and equipment with great success. They are hard to beat.
These are the crimpers I use:

They were $55 in the Snap-On truck 25 years ago. The exact same pliers are sold by a couple other companies.

I have never used the Amazon ones, but from the photo it looks like the removable jaws may be die-cast (One of the one star reviews suggests they are plastic?). Anything die-cast that will have any amount of pressure on it makes me nervous. That was not the complaint in the many one star reviews though.
