What to use to seal pipe?

[ramses]

I've used copper "anti seize" tape on my hybrid. It's basically thick, wide teflon tape.

You also need to make sure you apply it in the correct direction. You should wrap it in the direction that would make the fitting tend to tighten the tape, rather than catch the edge and unwrap it.

One more quick question. How do I calculate the pressure needed to rupture burst disks? If I recall correctly, there's a constant unique to the material that is needed to calculate this. What is that constant called?

Yes there is a constant K for determining a standard for when a burst disc of a certain material should rupture. You'll need to experimentally find this constant.

The general form of this equation is well defined in this document

And K can be found experimentally by plugging in your burst pressure to the following equation:

K= (Ultimate Tensile Strength * thickness)/(Burst Pressure * Diameter)

Thanks for the information.

Funny seems a post of mine got deleted or just disappeared.
I basically said that I found some of the pink teflon tape lying around and used it. Working pretty well. So now I'm leaking less than 1/4psi/sex at 80psi. Not bad.

must ignore hilarious typo...
anyway, 1/4psi/second could be the difference between a combustable mix and too rich of a mix on a hybrid, so you probably need it completely air tight.

[Gun Freak]

That's way too fast of a leak... You want it 100% airtight for reasons like LnL stated.

I won't.

This is what I use. It's rated to 10kpsi.

LOL, the director of that video should have asked someone how to properly use an adjustable wrench. The movable jaw should lead the fixed one.

edit* Being an HVAC-R serviceman, leak lock is my go to sealer.I do use quite a bit of yellow gas tape when I don't feel like getting messy thoughhttp://www.highsidechem.com/leaklck.html

Loctite 270 ! good to 4500psi !

Incorrect. The fixed should lead the movable jaw. Loosen a wrench and pretend to tighten a bolt, and you will see that this way exerts less torque on the movable jaw.

After some searching and re-searching, followed by trying it for myself, I've come to a conclusion... you're absolutely right. All the old timers dun taught me wrong, donkeys. I figuratively retract my previous statement, but leave it literally for the sake of context.
