    Just saw these on motorcycleMD.com; anybody seen or used them?

    FAST AND EASY PROCESS
    1 Step solder and seal process for all your connections
    WATERPROOF
    Insulation tubing has unique dual-walled design: polyolefin tubing on the outside and hot melt adhesive inside. When heat is applied, polyolefin tubing reduces in size and adhesive flows inside the insulation. Dual walled tubing ensures waterproof seal and prevents wire corrosion.

    Old technology, but a very cool marketing concept. Sort of expensive in my opinion, unless you were putting together an emergency kit or something... it would be great for that. Most likely only a couple of sizes in the kit would end up being used for almost everything vehicle, so if you were doing a complete wiring job it would probably pay to just buy bulk in the sizes you need.

    One of our older mechanics used them as crimp connectors because some parts guy handed them to him and didn't mention that they were different. Needles to say they didn't work very long as a crimp connector.

    They've been common in aviation for many years. If you use some liquid flux on the ends of your wire they work better. I used them as an avionics troop.

    I use bare crimp splices and (preferably adhesive lined) heat shrink on bikes as vehicle wire conductors aren't always pristine and crimps work fine, but those splices should serve you well if you like solder. Do a couple for practice as with any splice you've not used before.

    If you stagger your splices you won't get a bulge in your repaired wire bundle.

    Thanks all for the replies. Not so *new* - I guess I missed seein' those from bein' stuck way up here in the toolies.
    I was just thinkin' they may be helpful for some new builders as an option to help with the often challenging and mystifying world of wiring.
    TNC.

    Not really a toolies thing because they aren't stocked at auto stores (which have those shitty insulated crimp splices instead). Definitely an industry and military thing.

    One thing they are good for is repairs on installed wiring where you can aim a narrow heat gun nozzle but can't swing crimpers. Get a few for your stash. They don't go bad.

    Grote makes a similar type connector. It’s a crimp type with heatshrinkable soft plastic and lined with glue. Like them in tight places I personally
    despise the hard plastic insulated crimp connectors sold at auto parts places they are literally garbage

    Hadn't seen them, but looks like a damn good product for roadside emergency repairs.
