Heat shrink

[rallystyle]

So i have some wiring i am cleaning up and eliminating some connectors in my holley efi harness. does anyone have a recommendation for heat shrink ? it will be in the heat of the engine bay. thanks.

I'd look for a marine grade heat shrink. It has an inner coating of adhesive to seal the wire ends.

I use double wall self sealing that shrinks 3x if I remember right. I get it on eBay.

I agree with the above posts. I get mine from Amazon. $10-$20 for a box of assorted sizes (depending on diameter, whether you want adhesive lined, which I recommend, and shrink ratio).

Harbor freight has a nice assortment of the marine shrink tubing for about 8-9 bucks. I usually keep 2 to 3 sets so I never run out.

1/4” is what I use most of the time:

Raychem DR25 is the stuff to use in the engine bay. You can get it at prowireusa (see Strip's post above), McMaster-Carr, Fischer Motorsports, etc.

Amazon has dealers that sell it in 100' rolls.

Yea..It's heat shrink..But it is NOT the good stuff. The good stuff as said is the marine grade w/glue in it.

Please use RED heat shrink on your Positive terminals.
