Advice on using heat-shrink tubing requested


Recommended Posts

Guys, I could use your recommendations:

• What tool you guys use to shrink 'heat-shrink' tubing?

• Is all tubing created equal or is there a brand you would especially recommend?

• Do I have to solder the wires first or just twist them if I'm using heat-shrink?

Thanks,

Alex

Solder all connections for best connection and durabilty.

You can use a cig lighter if you're carefully.

I usually just lightly brush the soldering iron against it.

IMHO the shiny vinyl kind from radio shack sucks.

It doesn't seem to shrink as well.

Try to find the kind rubbery kind with a flat finish. You can get it at a hobby shop that sells RC cars and planes.

It shrinks up better.

But remember it's only gonna shrink maybe 50% so get the right size.

Definitely best to solder.

Alex:

Ditto on the soldering. Always a better practice.

A good way to shrink the tubing is to use a heat gun or a hair dryer. That gives you good control of the shrinking and avoids possible burn-through.

In a pinch you can also use a cigarette lighter as was suggested, or a match. With both of these methods, be careful to not get too close to the tubing to avoid burn-through.

There are different gauges of wall thickness for heat shrink-tubing, but I don't know of specific brands. Some "commercial-grade" heat shrink tubing leaves almost the equivalent of the thickness of the covering of a regular wire after the tubing has been heat-shrunk.

Regards, Maurice.

If it were me I'd just use heat shrink, because that's what I have.

It would probably work fine.

But keep in mind that regular heat shrink tubing won't necessarily be 100% water tight.

I've seen some auto splice crimps with heat shrink on them.

They have some kind of hot glue type stuff in the ends that seals the ends up when you shrink it.

The glue like stuff is the dual wall shrink tube.
