How much insulation should I strip off the wires for the Ancor heat shrink butt connectors (adhesive). My guess is 5/16 of an inch?

The Ancor offical site is silent on this detail. I need your help.

In any crimp connector, the insulation should be removed from the wire so that the entire crimp portion of the connector is filled with wire, and the insulation butts against the connector or has only the smallest gap between the connector and the insulation.

Hello Richvi,

Jim is on the money.

Just stip enough of the wire jackets to be joined so you don't see any more than like a 64th of an inch of copper(or none) sticking out of either side of the metal sleev inside the shrink-tube..BUT, make sure that you ARE filling the bore on both sides of the center "dent" with stripped copper conductors.

If you want to make it a "Hundred-Year" connection or splice you can also squeez a small dab of Di-Electric Grease (blue Corrosion Block grease or clear Merc. Di-Electric)from a tube into the metal part of the sleev before you do your crimping and heat shrinking. Like I said, terminations done that way will probably still be very sound electrical joints in 2106...

I have done a couple of hundred re-terminations like this, with a little worm of blue Corrosoion Block grease from a squeez-tube, during the restoration of my 28 Outrage over the last several months and I KNOW that I will NEVER have any termination bugs in my wire-harnesses...period!

Yeah, it's a bit more time consuming and some people may consider it a bit obsessive, but it gives me satisfaction to know that I have done it Super-Right!.

I just did this to my 16 classic and it was a pain in the neck, but the wires should last. In some cases I used the heat shrink connectors, additional heat shrink tubing, and the liquid electrical tape as a triple guard system to keep out the corrosion.

listen to all three of these guys, they did it the correct way, and will not have any problems, take your time and do the same you will not be sorry, I even solder my crimps before heat shrink, I also off set the cuts so you do not have a big bundle in the middle of the wire, Then I heat shrink all of them together, Just like reborn stated 2106 my connections will still be working...good luck
