Posi-Twist Connectors (New Electrical Product)

[BoomerBob]

Got an email today showcasing these new Posi-Twist connectors. Also called Posi-Lock. I hadn't seen these before so I thought I'd share the info here.

it looks like a glorified wire nut. the only difference being threads...?

i wonder how they would hold up in a high vibration environment.

I think that's where they would excel; that and being more secure and more water resistant. Could even fill the one end with silicon to make it waterproof.

No doubt someone will say these have been out a long time and they are nothing new. It wouldn't be the first time I was late to the party.

I wouldn't use this in a house but for a car or bike where they get a lot of movement...

That'll be me... they've been around for at least 5 years now. The Posi-Tap is the product I know better:

But the company has a few different products. And this is the more direct site where you can avoid Bezos:

I've used the Posi-Tap's before on my truck and boat.
Only used them a few times but have no complaints.
I think I first saw them about 10 years ago?

The only downside I can see I they are pretty bulky.

Thanks for sharing your findings. But I have to agree with other members, they have been around for a while 10+ years.

Wedgy, I have used them on a number of things and they're OK, but not as awesome as I thought they'd be. The idea is cool, but there's a fine line between being hot enough to melt the solder, and being too hot. When that happens, the shrinking of the tube creates a geyser of molten solder out of the hole you melted in the side of the tube.

Use these a lot and really like them.

Sounds like you need a heat gun that uses an adapter to direct heat to a specific location vs all over. I've been using these type of connectors for a while and have never had any issue with melting through the shrink tubing. Additionally, for further waterproofing and coverage, I always use separate shrink tubing over the connector that covers wire to wire.


As per the connector in the original post, I think these would be great for some low voltage home applications, but I don't think they'll stand up to exterior truck use and are quite bulky to use for interior of the vehicle where you usually have to tuck the wire behind a panel or out of sight. Plus, constant vehicle vibrations, over time, can always jar something like this loose. A soldering connection with some shrink tubing or tech-mesh usually prevails in this area. If I want a waterproof and quick connection for exterior use I'll stick to using a Deutsch connector.

I have those waterproof ones and honestly think they are not that great. Half of the time you cant direct the heat properly and end up with a crappy joint. Or damaged heat shrinking. Seem to work a lot better in the smaller gauges of wires. I rather just solder the joints of wires and then slide heat shrink over the exposed soldered surface and shrink it down.

When I saw the video the first thing I thought was that must be some really tough shrink tubing or very low temp solder. I just solder then shrink tube after.

i'll stick with soldering or quality crimp connectors (not the autozone crap) and shrink tubing my connections. that method has been working for me for 35+ years on assorted A/C V-Dubs and 6 different toyota trucks

these things do work pretty good
