[music] 00:05 Speaker 1: I’m just about to apply some
of this Teflon tape to the thread on this pipe. Now, that can’t be too difficult, seriously.
Let’s have a go. So, I get out tape, and I put it on your pipe, and start, oop… And
start winding it on like that, and we just… Hang on. That’s no good. That’s… Duh, sticky
stuff. Let’s get the end square, flat, and just start winding it on like… Oop! Like
that. Hang on a sec. Just like that. Now, wind it on and I just… Is it clockwise or
anti-clockwise? I’m not sure. 00:58 S1: G’day, knuckleheads! Uncle Knackers
here. Did that look familiar? Well, if it did, keep watching this video and I’ll show
you how to do it properly. Let’s go. 01:07 S1: Now, a couple of quick things before
I start the demonstration. Teflon tape is known in some countries as PTFE tape, and
the reason for Teflon tape is that when applied to a thread on a pipe, it provides a watertight
seal and it’s often used on things like water lines, gas lines and drainage pipes. Now,
one thing to remember is that, you don’t need to use Teflon tape on a compression fitting.
Now, a compression fitting is one that requires a gasket or a cone to provide the water tight
seal. But the P-trap underneath your sink has got a rubber gasket. That provides a seal
and not the thread. So, you don’t need Teflon tape. 01:50 S1: Anyway, enough of that stuff. On
with the demo. So, this is how I do it. I get the Teflon roll itself and I’ll put it
over my index finger, just like that. And then, I’ll grab the Teflon tape and I’ll lay
it on top of the thread and hold it with my other index finger, this one here. And then,
I’ll start to wrap around the thread, keeping it nice and tight in a clockwise direction,
which is very important, and I’ll explain why later. Now, I’ll wrap it around four to
seven times and I’ll make sure that I’m one thread back from the end of the pipe. Now,
the reason for that, I’ll tell you in a second. I’ll just finish wrapping this up and I’ll
snap it off, and there you are, all done. 02:47 S1: Now, I keep it back one thread from
the end because if this Teflon tape is flapping over the end, when I screw my fitting on,
a bit can shear off, go inside the pipe, and it may foul up a valve or something like that.
And the reason why we wind it on clockwise is that the fixture itself winds on clockwise,
just like this. Now, if that Teflon tape was wound on in an anticlockwise direction, it
would unravel as you screwed this on and make it useless. So, we now have a watertight seal. 03:33 S1: Great tip, Knackers! And as per
usual, if you found this video useful, subscribe to my channel. The button’s down there; thumbs
up, the button’s down there as well. And I’m also on that Facebook thingy at DIY For Knuckleheads,
so check that one out. Anyway, I’m off to connect a [03:52] ____. So, till next time,
I’m out of here. Cheers.
