I always have a roll in my tool box at work.
I use it for oxy act and compressed air tapered fittings.
If you don't use it the fitting will probably leak.
Make sure you put it on the right way(left right)
Plumbers tape is just Teflon.

It is very easy to do a leak test.
All you need is water soap and a brush or rag

You don't need plumbers tape on a regulator to high pressure bottle fitting.
As they have a seat.

When connecting high pressure bottles to regulators always crack the bottle.
Wipe the regulator seat off with your finger.

Ive had the typical white and also orange stuff before... The orange "seemed" thicker and more manageable but not sure if that had to do with anything or just manufacturer protocols.

In the plumbing world there are generally 3 types or of Teflon tape used;
White, yellow and pink(All 3 types are a available at Home Depot for under $5, don't go to a plumbing supplier/specialty shop, you will pay upwards of $25/roll).
White is the thinnest t-tape, Yellow is double the density of white, and pink is triple the density of white.
For small fittings/threads you probably should use the white t-tape.
Be careful not to wrap or use too much t-tape on the threads, too much t-tape (and over-tightening) can actually crack the fitting. A general rule of thumb is to wrap the threads 3 times- make sure you only wrap the threads.

I almost always use the pink t-tape when working, you can stretch it as you apply it to make it thinner, although I don't recommend stretching it unless you know what you are doing.

I do teflon taped fittings at work about twice a month! White Mil-spec teflon tape on all the AN Fittings we do. Two complete wraps. Torque fittings to spec! The stuff we use is twice as thick as the hardware store variety.

I use the pink type almost daily at work, and 3 layers is pretty much as I'd ever put on. The thinner white stuff is easier to apply in some ways- maybe because it's pure Teflon-but needs more layers to properly seal. I'm pretty sure the pink stuff we use at work is a composite of some type...

I use pink as IIRC only the pink and yellow are good for gas lines and that's the last thing I needed tape for. Of course they only sell it in 3 packs s o now I have a bunch I'll likely never need.

What about the Black? That comes on high pressure air fittings? Anyone know anything about this?

As far as I know the black is brand specific.
Ninja sells it for it's tactical look, pink doesn't go with camo I guess.
For high pressure air, oxygen etc, the industry standard is green in colour.
This meets a no oil/grease etc. purity standard.
As Logtec has said the different colours are related to density and thickness.
Use is determined by application and pipe size/material.
Generally only used on tapered pipe thread in place of pipe dope.
Fills the voids but mostly lubricates the threads.

Why would you use tape on AN fittings?
NPT/tapered thread is not common on aircraft except for some adapter fittings.
Just curious.

These are DeHavilland aircraft from the sixties. That is the best answer I have! :?:
