Never heard of using Teflon tape on the threads before. If is a common practice ?

Not that I’ve ever heard. A copper crush washer (any auto store) is my preferred method

[Tomcatfixer]

That's a new one to me, too.
Stick with the crush washer or dowty washer.

I've been doing a bunch of OEM certification classes and the only mention of it I've seen is to NOT use it because it could potentially get into the lubrication system causing a blockage.

Those plugs come with O Ring and washer. No reason to use Teflon tape. Teflon tapes is for sealing tapered pipe threads not for sealing straight threads.

Oh the perils of looking at stuff on the internet!

Is it a water pipe union? No. Did it leak without the tape? No.

It is truly astonishing but I have seen plumbers use Teflon tape on flare joint, compression joints and O ring joints (many commercial toilet fixtures have O rings.

If you are lucky, it does no harm, if not, you can cause a joint designated for a different form of sealing than tapered threads to leak.

Basically its gross ignorance of how a sealing joint works. You would think the Union would train its plumbers correctly but nope.

And Teflon tape will break off the threads and get into the mechanism and I have seen carnage caused by that crap in the mechanism.

The only place I would use it was one time gas line joints and joints for air breathing (Flight simulator using compressed air to emulate oxygen mask ops)

There is a line of goop called Gasoila that is far better than Teflon tape (or goops)

And while it takes a long time, most Teflon tape is not oil rated. Yep, diesel or gasoline tapered threads will leak in a few years because the petroleum eats through it. Most annoying to have to go back and fix a bunch of those joints.
