Hey brian here, thanks for watching this video caleb does a really good job of showing a way of crimping. That makes for a better connection. That's going to last longer depends on a few things. I'll kind of show you at the end a few other techniques that i use in order to make a crimp that's going to last, but big thanks to caleb for making this video hope you enjoyed all right.
So what i've noticed a lot of guys do is when they're making a crimped connection with these spade terminals. What they'll end up doing is they'll only do a single crimp, where the exposed conductor meets the metal side of the spade terminal, which is perfectly fine until as it keeps getting tugged on and off. You see how it's bending like that. It's you know it's bending independent of the insulation of the wire.
Eventually, what will happen is this will slip off, as this connection becomes corroded, it's just crimped down to the threaded conductor wire. So what i want to show you guys real quick is the importance of double crimping. We got a brand new spade terminal here, we're going to cut off just a little less than what you would expect to see we're going to make the first crimp. Just you know, as usual, to get get right there on that conductor and then what we're going to do is we're going to slide down and then right there on the insulator we're going to crimp that down as well.
So now the spade terminal is connected to not just the conductor wire, but also to the insulation around the conductor, and it's not going anywhere if it bends, you see how the the difference now is not bending independently it's bending with the wire it's going to keep It from scoring that conductor it's going to keep it from snapping off in time. Also. Another thing i've noticed is that when you're look when you're using a crimp tool, make sure you're using the insulated side, if you're using an insulated terminal and then here's the non-insulated crimping tool side, if you're going to crimp a crimp, a connector that is not insulated, There you go all right so just to follow up on caleb's double crimp um. One thing to point out is there's different types of insulated terminals.
These are actually the ones that i use most often now, which is actually a heat shrink terminal. So after i make my crimp, you know you heat it up and that shrinks it down, and especially with the advent of battery powered heat guns and then also, i use a little butane, a little butane heater as well. In order to shrink this down, it makes it really nice, especially for just protecting the entire terminal, because, as you can see, this extends pretty far back along the wire, which kind of solves part of the problem. That caleb was showing the thing i want to show you here, though, is the barrel on this one's really narrow, so that might make a double crimp tricky.
Also in this case, if you choose a smaller size, you won't necessarily always be able to get the insulation under the metal part under the barrel to do a second crimp, and so in some cases you know if you have a terminal like this, a double crimp May not be practical, i still like it in this sort of case. So if you were going to use this wire here, you would strip it back. Very short sort of like caleb showed strip it back. Only about that far, maybe even a little shorter, might even snip off a little bit of the end there and then push the wire all the way in against the stop. Now i can crimp here and here and that will tighten it against the insulation as well, which will make a better better connection. So i really like that, but another thing i want to show quickly is: there's also a couple different types of crimpers for insulated connectors. So this is a ratchet action crimper for insulated connectors that i really like it tends to get it a little tighter and then you've got your insulated connector crimper. Here now some people will use this.
I mean i've used this for most of my career, even for insulated connectors. Just keep in mind when you do that, you're going to make a little indent that could you know, could potentially create a short circuit with a heat shrink. Connector you're not in as much danger because, as you heat shrink, it back it'll generally kind of self heal, but it really just depends on the quality of the connector. But one other thing.
I wanted to show you quickly, if you're ever, connecting to like a thermostat wire like a typical 18 gauge, solid strand wire. I've showed this before, but i want to just kind of double down on this. What i would do is strip it double long and then you bend it over so then you double it over slip it into the connector, and then you make your crimp and that grips a lot better. So now, when i crimp down on that, that's going to make a much better crimp, so we'll just do a demonstration.
This is a blue terminal, so we'd use the blue crimp on this ratchet crimper. That is really really tight. You can see it didn't compromise. The insulation, and now, when i heat this up, it's going to give me a nice protective sheath and that's not going anywhere, whereas if i had crimped down on just a single strand and that could potentially give me a problem so again, i i love the double Crimp technique, it really just depends on the terminal that you're using the size of the wire there's some other factors there.
If you ever find that you're having trouble with your uninsulated crimper making it really tight, then get one of these ratcheting crimpers to help out all right. So that's it thanks for watching, i hope to catch you on the next video you.

AMP PIDG The original double crimp. Still available at TE Connectivity.
simple and effective. I've learned so much from you all. you're a blessing.
I started doing this thanks to you. Thank you.
Great video…. you could talk about crimping wires for an hour… the one thing I would add though is the ratcheting crimpers have an adjustable dial to increase or decrease the crimping strength
I use quality connectors, be careful of the cheap crap. Some of the cheap ones can literally be ripped apart with your bare hands. I use the Klein non insulated crimp tool on insulated and non insulated connectors. I stake the connector and tug on them. The better the crimp, the less heat at the connector, the longer the connector lasts. I have never had one fail in the 22 years I have been doing it this way. If damaging the insulation is a concern, electric tape works great to cover it. Heat shrink tubing works even better. A staked connector will probably out live you.
I would’ve liked to see a demonstration and result of the shrunken connection after heating it up. I like the idea of doing it like that
When using the non-ratcheting crimper, I've heard folks talk about paying attention to where the seam in the connector is, and placing that side of the connector against the concave part of the crimper…
Great job and video
If I’m understanding this video correctly we are showing using some of the metal crimp ring to crimp the insulation? That seems like a really bad idea. A better solution if you don’t want to buy shrink wrap connectors is to just buy a roll of shrink wrap tubing and finish off the connection with that
I have always used the double crimp method, it's how I was taught to make my connections years ago when I was a teenager. Great video but Bryan's audio was awful
Very important data! Service area Kanata??
Good stuff Bryan! Keep the tech tips coming.
No thanks for me. Use the heat shrink or get the proper connector with a separate crimp for the insulation.
Good vid. I Do Like the Look of that Wirefy Crimper. I Have Been meaning to get one of those as The Klein crimpers take a Great deal of Force & that is not desirable anymore. I have been using those Klein crimpers shown for the last 40 Years. They do provide a Great crimp & Have served me well.
Yah Bryan is back
Thank u for sharing .from philliphines👋
Well done. The best explanation for this. No matter how long you have been doing the trade always try to learn and relearn something new every day. Thanks again for helping me do this. Service area Ottawa??
First year college student, I love your videos, I just started watching and I can’t stop.
Where are you a located at?
I’m going to give the double crimp a try next time Are you in Orleans ?
I've had a Panduit CT-1550 (I think) since 1997. It gives consistent crimps every time.
Love the videos keep them coming. Thank you
Sir do you guys work with inverter AC?
I follow your page and I'm a huge fan. I dont miss a single video. But I dont see videos from inverters Air Conditioner. Can you do some?
I love how you care about every detail. Keep the videos coming!
I actually like the idea of crimping the insulation too. I'm gonna try it and report back. Thank you
As it keeps getting tugged on? Who’s tugging on connectors repeatedly after they’ve been installed? Lmao
Nice tips.
"a little butane heater" Bryannn show us your mini torch!
I have noticed over the years that the wire sizes and terminals have changed. It used to be that a 14 ga wire would not fit into a red terminal and the wires fit tighter in the terminals. If you want to have a positive crimp like that use the terminals that have the additional metal sleeve that would crimp on the insulation. Are you in Kanata ?
Your truck has ants.
Great Video. Thank you for sharing ^_^
What is the fold out table he has????? Link or description
Just use the crimpers correctly. I don't like that idea of crimping the plastic to the rubber insulation on the wire. Are you in Nepean ?
Great tips, except solid wire, they should not be crimped. Solid wire does not have the rebound capacity to stay in the crimp. It’s better to put a length of stranded wire with a wire nut then a crimp connector. On the stranded end.
I like the ratcheting crumpet when making a few connections. Consistent results with them. Service area Barrhaven??
Thanks to the guys at kalos. You guys always take pride in your work and take the time to share. 👍
