[Shop-talk] Wire splice sealant

[Jack Brooks]

I will second Wirefy products.  I’ve used their shrink tube, terminals and connectors in my Sprinter van build.  Good, solid performance from a mundane component.  Their crimper is rock solid too.

Glue-lined heat shrink is cheap, easy, fast and effective.  I use it on my boat for every wire splice putting it over a glue-lined wire splice connector or end terminal.  Just remember to slip the heat shrink on before you finish the splice or attach the terminal.  I've been very pleased with the pre-cut tubes from Wirefy from Amazon (https://www.amazon.com/dp/B09NW7954L?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_4) but you can also get good quality bulk rolls from Amazon which can be more economical than the pre-cut selections.

Jeff looks very interesting. I’m guessing it comes in a range of sizes? Where did you get it from?


The answer is always McMaster-Carr

But we probably got it from DigiKey back when I was buying it.  You will have to poke around in their catalog to find it, though.  This phone screen is too small.

Thanks, Ron

We used to get 3M heat shrink tubing with glue/sealant inside.  I never had a problem with that, and it was 1/10th the trouble that this appears to be.

Seems crazy expensive, but I do lots of marine wires and if they are really better, I can make the case to buy it.

Anyone ever use it?  There is only one review, and it seemed their were problems with the order.

Looking forward to what you all have to say about it.

Couple of pluses,
Seems to be a very good seal
Don't need to worry about putting the heat tubing on before the connection.

Minuses
I guess you have to used their butt connectors (not really)
Mold release also
Might be hard in a tight spot.

Do you think it's a normal glue gun?  I have a nice cordless one I would rather use.

Thanks again
