200pcs Heat Shrink Butt Connectors,Alkaidstar Insulated Waterproof Electrical Wire Connectors Crimp Marine Automotive Butt Splice Terminals (3Colors/3Sizes）

I use these mainly for van projects, both inside & out. They work great for making a tight seal around the wires. I was completely sold when after looking at some wiring for rear flood lights had been hanging down for a while getting hit with mud, water & snow with no issue whatsoever.I would recommend getting a small butane torch. It's way faster and easier than a lighter.

Worked great for current project. Drank and sealed connections very well with very firm hold on wire when properly crimped and did not shear or tear under pressure while crimping. Only found 1 cull, missing insert from sleeve in package.being boxed and organized is a great touch rather than just bagging.

I've used just a few of the Electrix Butt Connectors, but they seem to work very well. Crimping is easy and holds well and the heat shrink tubing bonds tightly with the wires. An excellent product at a reasonable cost.

They worked great and 50% the cost of connectors at the boat stores.

These work great! Needed to connect some wiring, but didn't want to use Wago connectors as I worry about the wires snagging on things with the angled connections. With these I was able to connect the ends of two wires straight together without soldering, and then closed the connectors up with my heat gun. Perfect!

These are ok. The ring connectors are thin and can break off if twisted too much.

Really good quality. When you heatshrink on the wires it really holds.

Pretty much what you'd expect. I have to say though I'll probably never go back to using regular butt connectors after trying these that have shrink tube built in
