Excellent way to join wires and have a solid connection. You must watch for some possible solder leakage that could result in a short. Just clean up the end.

These are a lot cheaper than the other alternate and they work just the same. Same size. Shrink up just the same. I will use these from now on.

These work great, provided you have the proper real heat gun. I use them for terminating shields, and splicing in a ground wire that can have a contact crimped on for D-Sub and other connectors.

Great for splicing or connecting ground on shielded wire. 0.25in works for two conductor shielded. The smaller size would only fit single conductor cable.

These are good sleeves but there is a gap between the .125 and .250, I wish there was something in the middle there for making more compact connections where space is restricted. The .125 is just barely big enough for 2 wire, 22 ga shielded, if you dont comb the shielding back over the insulation. They have the lowest melting point of several I tried and if you check the manufacturer datasheet you can see the solder melting point for these is the lowest of several possible solder variations.

These little gadgets are wonderful. They make a nice weatherproof soldered connection using just a heatgun in a few minutes. Spend some time and rig up some clamps to stabilize the free ends, and these things work great.
.125 is the smallest, and will work down to #20 and possibly #22 wires.

Solder Sleeves do the nicest professional looking job. Aircraft Spruce is a great source to buy fresh product in both small and large quantity.

The small works for single shielded 22 awg and can barely fit one 22 awg ground. The medium size is better for twisted pairs and three conductor wire. Works well.
