Connect hoses with teflon tape


Hi all! I'm new here and starting a project.

I need to replace a Phoenix garden tub faucet. I have the new parts, but get confused with the following:

"Wrap end valves with teflon tape. Connect flexible hoses to end valves. Apply 2 right hand wraps of teflon tape. Wrench tighten."

The piece I'm looking at is called according to their diagram - a "valve". What do they mean to wrap "end valves"?

Here's a picture of what I'm looking at -



I would assume that the part I need to wrap has something to do with the connection of the flexible hose as they mention it in the next sentence. However, where the flexible hose goes - the threads are "inside". See #1 in the picture. So, I'm wondering does the tape maybe go on #3 - only that has nothing to do with the flexible hose . . .

Also, should I wrap the end of the flexible hose too as it has threads?

I am lost . . . can you tell?

Wrap the tape around the items marked 2 and 3.

Only #2 needs it. You only need to tape tapered pipe threads.
The other one is a straight thread.
It's not going to do any harm, just not needed.
When taping there's a right way and a wrong way. Done wrong and the tape's trying to come undone as your installing it.
I hold the fitting in my left hand with the threads facing right. You start at the bottom of the fitting holding it in place with one finger holding it tight as you wind it around the threads making sure it's going into the threads.

Let me guess, that's Chin-glish documentation?

The idea is you wrap the threads for the water carrying connections. 2 &3 as suggested above. This will help keep them from leaking. You only want enough to help make the seal, not so much as to impede the threads from connecting fully. Thus two wraps around it are usually enough.

Just be sure when you're connecting hoses that you avoid twisting them as you thread them into/onto the fitting. Otherwise a twisted hose won't pass as much water/pressure and has the potential to kink or split.

Connect hoses with teflon tape


Figuring out which direction to wrap teflon is common sense, once you understand what you're trying to accomplish. Wrap the tape in the direction that you'll be screwing it on, so that while tightening it "tightens" the teflon tape too. So put it on in the same direction that you'll be turning the threads.

Basically you can put teflon tape on any metal thread, anywhere, whether it carries water or not. I use it on my pressure washer, my air compressor, etc. Unless the directions say otherwise, it basically can't do any harm. I'm not sure it always prevents leaks directly as much as it makes the threads easier to turn, and therefore get a tight fit (reduces friction in the joint). Tighter fits mean no leaks. It's very very thin stuff, thinner than it looks, so I'd use 2 wraps at a bare minimum.

There are at least three types of teflon tape. The white stuff is most common and general purpose. Pink is for potable water. There's also yellow, which I think is for natural gas.

Thank you all so much! I'm now trying to get my nerve up to shut the water off and disassemble the old faucet.

Needless to say . . . I'm shaking in my boots!

I'll post back with the results, but it will be a lot later!

Already, another question. You see the biggest threaded area (it is not marked) on the valve - the part right under the writing on the valve?

It says that I am to thread locknuts onto end valves and add flat locknut washers and it shows putting them on that area. That area (even though threaded) is not an area to put the teflon tape, is it?

In the picture below, the part I marked in black - it does "not" get teflon tape, correct?

And that is where I am to thread the locknut and locknut washer, but how far down do I thread it?

No tape there- use the lock nuts to adjust for your deck thickness.
Test fit the valve trim to determine how much of the threaded stem you need exposed on the top side. The instructions might tell you that deminsion

Connect hoses with teflon tape


I finally started the project this afternoon and was doing pretty good until I ran into the locknut under the tub holding the old spout. I don't have a wrench that will fit. I tried pliers with no success.

Any thoughts on tools that might work in getting it off?
