Default new to heat shrink connections?

If you have been reading here about heat shrink this, and connector that - here is your solution - after trying many different units at Home Depot and west marine - DUMP YOUR WHOLE ELCTRICAL DRAWER...

this is the best and least expensive fool proof way to go. Thanks to Elusive for pointing me here - delcity.net - an electrical paradise. Do not ask questions, just order these butt connectors that have heat shrink AND SOLDER in them for a perfect connection everytime... using a crimper that is ratchet style and won't let go until you press enuf...(watch your fingers!)

www.delcity.net
981005 - 18-20 ga butt connectors at .53 ea
982005 - 14-16 ga butt connectors at .55 ea
990160 - crimper at 34.00 ea

BTW, I think I heard delcity is owned by Ancor....

You didn't mention what are you using shrink them (heat gun, etc)

Btw- Learned about DelCity on THT

Heat gun with a hook type nozzle works really well: Nozzle is slightly longer than usual, closed on the end, and has a cutout in the side that has a slight hood. You can use lower temps, and direct the heat better (not melt anything you don't want to.)

For the last time, Home Depot does not sell boating supplies ........

Now this will not lite the grill, but it looks perfect for heat shrink - flameless

Glen,

Those look great, thanks for the info. We received a bunch of the crimpless, solder butt connectors with a kit that someone ordered and assumed that they were crappy butt connectors since the crimp area was so small, so we never used them. Now I realize that they weren't crimp connectors at all.

As far as heating them, the butane torches do work but I like using a butane soldering iron with a heat shrink tip. Weller or Master Torch are both very good ones.

Those were originally developed by a gal and her partner here in Pensacola. They called them Electralink, and are available through National Standard Parts, her company. They sell them out to different companies under a vast number of names.
I've been using them for years, with a couple of caveats; Don't use any more heat than you need to start melt of solder. Otherwise the plastic will melt through. Also if you can, start the heat from the center out, or away from the solder collar, or you will seal then end, which inhibits the flow of the solder, not good. Otherwise a great concept.

Glen that's great but it puts me in a quandary. Solder type connections are verboten by the ABYC because it effectively turns stranded conductors solid, making them susceptible to work hardening and failure. I didn't write the standard and I'm not here to defend it sooo..... I have placed a call to the E-11 technical advisory committee to get their take on these things. I'm thinking that because of the low temp, measured solder content they will prove compliant. Ill let you what they say.

Thanks bait, I'm looking forward to your findings. I was thinking the same thing but the way that I interpret the standards is that solder terminals can be used as long as they are supported in a way that does not subject them to bending, also soldering cannot be the sole means of connection. It is the last stipulation with which I have the quandary since these connectors are not crimp & solder.

Well I just got off the phone with Bob from ABYC. As suspected these are compliant as long as the solder is not the sole means of connection. You must use the crimp and solder variety. I think there is just enough solder in those to tin the inside of the connector. I checked the web site and found that they offer the combo type connectors. It would be nice if that vendor were made aware of the standards and labeled the crimp, crimp/solder units as "ABYC compliant" to assist marine shoppers. Especially since in '07 all NMMA builders will be subject to all applicable standards, not the ala cart 'e ones they choose now.
Cheers.

What else can you use for heat if you do not have a real heat gun? I had some of these connectors but could not get the solder to melt before the plastic starting melting. I was using a lighter - tried to keep the heat to a minimum - it was all I had. Would a hair dryer work?

bro a heat gun is about $20 at the dpot...well worth it
otherwise a hair dryer is 2nd best or a small butane torch
cig lighter will scorch the connector and/or insulation on the wire

Here's how I've been making my connections:






The wires are wrapped around each other and there are two layers of adhesive-lined heat shrink. I'm poor (and cheap), so I use a regular lighter to melt things. If you're careful and don't hold the flame in one area too long, nothing burns.

Yes, according to the manufacturer and as displayed in their instructional video (make sure you're not on dial-up if you want to watch the video).

Nice Western Union spilces Cooper. You'll never have a problem with them but their not "ABYC Compliant".

thank god for the THT tech staff - I just use the connectors because they work neat...good to know that they are compliant - not trying to be sarcastic here...always amazez me how many people will investigate stuff better than I will....thanks!

It really pays off you know, doing the research and using the right stuff. Can you imagine re-wiring your whole boat, even up to the windlass with welding wire and solder joints just to have some know it all (he thinks) surveyor tell your buyer or your insurance company that you gotta replace it all? Same with all those miles of Napa fuel line I always see. Im not really a research nut, just happen to know this one...
