My how-to publish on soldering yielded some suggestions from readers asking for my opinion of heat-shrink butt connectors.
Yeah, I do know. I have been utilizing these for years and the identify nonetheless makes me chuckle. Sadly, my equipment calls them “solder sleeve connectors” however they’re the identical factor.

So, what are heat-shrink butt connectors? When ought to (and should not) you employ them? And the way do you employ them correctly?

Solderless, crimpless, butt connectors. All you need is just a heat gun to create a solid, weatherproof joint.
Warmth-shrink butt connectors (yeah, I am nonetheless guffawing) are sleeves of heat-shrink tubing with a hoop of solder within the center and two rings of adhesive at every finish.
You apply warmth, and the solder melts to affix the wires collectively and the glue softens to create a weatherproof seal.

So, when must you use a heat-shrink butt connector?
- When you want to make a powerful and dependable electrical connection between two wires.
- When you want to defend the connection from moisture, corrosion, or different environmental elements.
- When you do not have entry to a soldering iron or haven’t got the talents to solder the wires collectively.
- While you need to keep away from using crimp connectors which will work their method unfastened over time.
This is when not to make use of a heat-shrink butt connector:
- When the wires are too massive to suit into the connector.
- When the wires have completely different gauges (thicknesses) and the connector is not appropriate for the smaller wire.
- When the wires are uncovered to excessive temperatures which will soften the connector.
- When the wires will likely be uncovered to high-vibration environments, which might trigger the connector to loosen over time.
As for voltages, I’ve seen these connectors rated to 600 volts. Nonetheless, I’d by no means use them for something greater than 12/24V automotive or marine functions.
Additionally: That is the right mini electrical screwdriver
For AC energy, I would use a Wago connector (these are rated to 32A/450V), however I all the time suggest getting skilled recommendation when coping with energy traces.
Easy methods to use a heat-shrink solder butt connector
Strip 1/4 inch of insulation from the ends of the wires that you just need to join. If doable, twist the uncovered wire strands collectively to create a decent connection. (This won’t be doable with some wire.)
These connectors are available a wide range of sizes. Observe the steerage on the packaging as to which measurement to make use of (and put the lid again on the field once you’ve chosen one so you are not enjoying pick-up off the ground with the remainder of the butt connectors).
Slide the connector over one of many wires, ensuring the wire is inserted all the way in which into the connector. Repeat this step with the opposite wire.
Place the connector so the uncovered wire ends are touching one another.
Use a warmth gun or a lighter to warmth your complete connector till the solder inside melts and flows across the wire strands. Be certain to use warmth evenly to all sides of the connector to make sure a great connection.
As soon as the solder has flowed across the wires, permit the connector to chill utterly earlier than dealing with it. The solder will harden because it cools, making a safe and everlasting connection.
Examine the connection to make sure that the wires are securely linked and that the tubing is tightly sealed across the connection.
Wires aligned and prepared for the warmth to shrink the connector.

Personally, I am not a fan of utilizing bare flames to shrink the butt connector, as a result of, properly, issues can burst into flames.
I discover utilizing a hot air gun from a rework station to be safer and fewer dramatic.

An ideal joint!
I like to complete with a little bit of adhesive-lined heat-shrink over your complete restore, giving it additional stability and weatherproofing.
Additionally: This has changed my multitool for a fraction of the fee
Bear in mind, if you are going to do that you want to match the heat-shrink onto the wire you are becoming a member of earlier than becoming a member of them along with the butt connector.

That is a restore to be pleased with!
