    So most of us have used heat shrink connectors from companies like Ace and Lighting Shrink. But have any of you ever used the COLD shrink connectors from 3M before?

    This is an interesting product. Looks like it would be a time saver.

    If you haven't heard about it before, check out this YouTube video about it.

    Now, at first glance it doesn't seem like a very water-tight seal. But then I dug a little deeper. On this page it says the stuff works in "underground and submersible applications". Submersible? Wow.

    Then on this page it says it is "Water reisistant" and "meets the water seal requirements of ANSI C119.1"

    I'm not sure this is currently competitive in price with the heat shrink connectors we all use. But it's interesting stuff, nonetheless.

    Your thoughts?

    Interesting, but I wouldn't trust it.

    It's 3M, and rated for 1kV underground AND submersible lines. Why wouldn't you trust it?
    If it were something that Harbor Freight just started selling, I'd be with you, but 3M?

    I too wonder how well it works. Polyolefin heat shrink is pretty abrasion resistant, and the stuff with the hot melt adhesive inside is quite waterproof.
    I wonder if this is tacky on the inside, like the butyl adhesive on the underside of flashing tape. That would take care of the water issue.

    I wouldn't mind trying it out.
    I'd like to know $ compared to regular adhesive heat shrink.

    Looks to me like it is for larger gauge cable not 10, 12, 16.

    It works great!! I used to use this stuff all the time installing exterior network antennas on USAF hangers, for sealing the coaxial connections. If it works for the Air Force...

    I would Imagine the cost each is between $7.00 - $25.00 each.

    I would Imagine the cost each is between $7.00 - $25.00 each for small Gage #12 to #6

    Correcting what I said: From what I could see online, the connectors being used and the cables being connected had large sheaths even if it was smaller gauge wire inside. In other words, I didn't see any of these connectors for use with our small diameter LV lighting cable. Maybe I missed it.
