Liquid Electrical Tape

Anybody used the above stuff?
I am thinking particularly of the spray can variety, but would appreciate any views.

Hi Brian,

I've used this Liquid Electrical Tape - LET
It's closer to liquid tar than anything else. Too early to tell how well it lasts as I rewired during winter.

Most of the fittings I used were heat shrink sealing terminals, crimp them on, apply heat and the collar of the fitting melts and contracts around the wire. I'm much more confident in these than the liquid electrical tape.

Hope this is useful.

Potting compound is good from rs supplies mix in the bag and pour best if you have a mould (plastic pipe)

Cheers

What are you using it for? Spray can doesn't sound like individual wires.

I've used it, it's messy and stinks. uses some -oluene thinner or something, not good in enclosed spaces. I prefer the heat shrink terminals like Iron Dials. Much better and easier in my opinion.

What I am thinking of doing is-
(this is to replace a bilge pump)

Use crimp butt connectors, crimping them, then heat sealing them, then using the liquid electrical tape to double-seal them, and then enclose the bundle of three heat/crimp connectors together in heat-shrink tubing. Then maybe liquid tape that.
Probably my electrical connections will literally live under water.

This should belt-and-braces the connections.
Or......?

You're even more thorough than me!
I used heat shrink butt connectors, individually covered with heat shrink sleeving, seemed more likely to achieve three small seals than one large seal around three butt connectors.
I staggered the joints so that there wasn't a wide point pushing against each other and mechanically weakening the joints.
So far so good (and a lot better than the previous installation)

Liquid Electrical Tape

Look for self- amalgamating tape, it's like electrical tape but it's thicker rubber type and adheres to itself, becomes like a boot, you can't unwind it off again

http://solutions.3m.co.uk/wps/portal...tape/?MDR=true

Usually about a fiver for a small roll

Brian, times have moved on and nowadays there are watertight electrical connectors available which do a super, professional job - no bugring about as we used to do. Here's some advertised on ebay.

Self Amalgamating Tape : 3M UK & Ireland

Usually about a fiver for a small roll

Just for info...self-amalgamating tape amalgamates to itself but it doesn't amalgamate to the surface it is wrapped around so there is no guarantee of watertightness.

Wow, thanks Jeff-just what the doctor ordered-and so have I.
Asked for 1st. Class delivery-should get them Tuesday.

I didn't even know such a product existed!
