Wirefy (new product)

[gsrick]

I haven't seen anyone mention these connectors here and I just ran across them from a blogger. Wirefy has some really cool products for making watertight wire connections. Check out their site for all of their other products, but the one I want to share is their Solder & Seal heat shrink butt connectors. Soldering a joint can be a real PITA some times but this looks so easy even I could do it. All you need is a heat source, no soldering iron to heat up and get burnt from. Check it out. I've just ordered my kit and will give my review as soon as I get it and use it. Also check out the T Tap connectors.

I haven't seen these before either, but did some youtubing and they look pretty cool: https://www.youtube.com/watch?v=24FjjIVpk9U

Looks good! I'd be cautious about using them on wires that are under tension because solder doesn't make a strong mechanical joint, but for most of what we do that shouldn't be an issue.

Might be a good product but I'd also be.concerned about the low temp solder and ability to give a reliable mechanical bond in areas subject to heat. Hopefully they've done their homework.

Low heat is 280 degF. Just lower than what is probably is a Teflon heat shrink.

Been using a similar product in aviation for years, they work very well when you use them correctly. A lot of people will over heat the wires being connected though, correct heat source critical. Aviation insulation does not melt lie automotive stuff.

Lets just say practice is a good idea, and by the way, they provide plenty of mechanical strength, when done properly!

Called Raychem solder sleeves

That's encouraging. Thanks!

I like the look of those. Think I'd pass the wire right through & twist them first before pulling them back in to the right spot....

another alternative I've used a bit... seem to be very reliable & very simple. I cover them with some heatshrink if I want them watertight.

The Wirefy t-tap connectors are evil junk -- they're just a variation on the dreaded Scotch-Lok connector. Please don't use these. For anything. Ever.


The solder sleeves are interesting and could be a nice compact solution in certain situations. I'm not sure I'd use them on stator connections; stator wires are heavily loaded relative to the wire size, and they generally live very close to the engine.


And yeah, I'll agree that Posi-tite connectors work very well. They're expensive and a little bulky, but they're fantastic for field repairs -- all you need is some way to cut and strip the wires. And they really are suitable for permanent use if your "temporary" repairs seem to stick around. I usually carry some in my kit.
