I am fully aware that the large majority of people recommend soldering a splice connection & I agree that is likely the best method . That being said , can anyone definitely say , that a quality , properly installed heat shrink butt connector is more than likely to be problematic at some point & tim…

Butt splices are fine when, like you just mentioned, all the parameters are met. Especially when soldering is not an option, like in tight spaces. Matching sizes of wire to splice and all that you already said. AFTER crimping the splice. . .give it a tug. the splices I absolutely HATE are the ‘‘s…

I think the biggest problem with butt splices is making a proper crimp on the wire. Using a well made crimp tool and the proper size splice should pretty much eliminate that problem. If the connection is exposed to the outside then sealing the connection (using heat shrink or tape) is important also…

The only guarantee is if you use a hermetically sealed butt splice. Otherwise the wire is exposed and will oxidize over time. No, heat shrink alone is not hermetic but they do make heat shrink and butt splices that do result in a gas tight seal after heating to melt the sealer. That being said, many…

Actually a properly done splice is better than a soldered splice, even if it is not hermetically sealed.

Actually a properly done splice is better than a soldered splice, even if it is not hermetically sealed. Mechanically yes. However, exposed tin-lead is less susceptible to oxidation than pure copper…the solder will wick up under the insulation. A butt splice always leaves some exposed bare wire…

A proper butt splice with stranded wire is superior both electrically and mechanically and more corrosion resistant.

Years ago an independent distributor of shop supplies offered a great deal of high quality merchandise. He had a line of heat shrink crimp connectors that had a tab of solder trapped in the metal tube that would melt at the temperature that shrank the plastic shell. A mini blow torch device with a s…

There’s also the POSI-LOCK connectors. http://www.posi-products.com/ Tester

All the terminals on every car are crimped, not soldered so a proper, sealed crimp connector should be as durable. The 2 key words are "properly and sealed. That can be tough to do. Under-car connections, I want soldered with heat shrink to seal it. Inside the car, crimps are OK. My preferences.

The butt connectors I’m considering using are themselves heat shrink , didn’t know they were made until recently . I’ve been familiar with the heat shrink tubes for years . I will also give the splices a good electrical tape wrap if I go this route .
