Jamie Hyneman puts ptfe tape on backwards.

This is one of the earlier episodes, I think where they were seeing if running in the rain got you more or less dry. Jamie puts the tape on in the incorrect direction. If it doesn't go clockwise on a standard right hand thread, it'll loosen itself up.

It’s directional?

Yep. When you screw on the pipe you want it to be pushing tape down not curling it up.

It’s not a big deal though. As long as it’s not torn you’re fine.

TIL. So it goes against the thread?

If you are right handed, hold the tape in the other hand to what you would find natural when applying it.

That doesn’t make sense to me at all?

Try reading it again. That’s one of the main advantages of written communication

After reading it again, I’m still confused. I’m right handed. I would naturally wrap it using my right hand. If I want it wrapped the correct way, and comfortably, I’d use my right hand. Switching hands would either be more work or I’d accidentally wrap it the wrong way.

I couldn’t help but notice that not only does that video never once mention dominant vs non-dominant hands, but actually used the same hand, their right, in demonstrating both clockwise and counter-clockwise application

So when I go back to reading it again, like you recommended, I find:

“If you are right handed, hold the tape in the other hand to what you would find natural when applying it.”

Why didn’t the person in the video take this advice?

wtf dude. Reading comprehension. Dominant hand has nothing to do with this; it was one of many ways to explain how to start the wrap. You are beyond help.

Dioxybenzone@reddit

Lmao so we agree, dominant hand has nothing to do with this. that commenter’s claim that it does doesn’t make sense, as I already pointed out.

Somehow I’m the one with reading comprehension issues even though you’re just now arriving at the same conclusion as my very first comment?

When taping go from right to left across the top of the pipe, and then under the pipe go left to right. That way when you screw on the connecting piece, it doesn’t try and peel the tape off, as it will thread left to right.

It goes on in the same direction you thread the pipe on. So clockwise on a normal threaded pipe, counter for reverse. The purpose is to prevent threading the pipe on from unrolling the tape by going against it.

HonkyHam@reddit

Ahhh righto makes sense

Red-Sun-Cinema@reddit

This is a misconception. You can put the tape on either direction and it works just fine.

No it isn't?

I am litterally a plumber dude, I use it everyday.
