Yeah the tape will stil let it ground. As the tape is twisted around the threads and sender screws in, the tape will cut on the threads, only leaving tape in the voids between threads. I myself use pipe dope teflon paste. Apr 27, 5. Messages: 11, Likes Received: I've just about given up on tape myself, like the rest of the guys. Let a little piece come off and get caught in the needle seat and you'll leave the tape alone also. Apr 27, 6. Messages: 1, Likes Received: 2. I've done more than a little plumbing.
Teflon tape is a lubricant, slippery, it allows fitting to fit tighter. Green thread seal tapes are required for oxygen applications, as it is grease-free yet does not allow fires to start.
Grey thread seal tape has a high density rating and is nearly double the thickness of standard thread seal tapes, making it ideal for taping up stainless steel threads, preventing seizing and galling. In short, thread seal tape is best used to seal up most threaded connections.
However, if said connection has a rubber seal or gasket, you also do not need thread seal tape. While thread seal tape is not difficult to use, it is not as simple as slapping on some good old duct tape and calling it a day. The way it is applied is vitally important, not only because incorrect application will fail to keep your connections and pipes watertight, but taking off wrongly applied thread seal tape so you can re-apply it can be a major pain.
The first thing to consider is to wrap it around the pipe in the correct direction. If you do it right, the pressure from the mating threads should end up tightening the tape around the pipe. Wrap it wrong, and the threads will work against it and ball it all up.
The trick is to wrap the tape in the opposite direction that the pipe is to turn. Follow these steps for the proper usage of thread seal tape:. Step 2: Place the end of the thread seal tape on the second thread from the end of your pipe and keep it stationary with your finger. Step 3: Begin wrapping the pipe in the opposite direction the pipe will turn, keeping the tape tense so that you can wrap it tightly onto the threads.
Step 4: How many times the thread seal tape will go around the pipe depends on the thickness of the tape, but for the standard variety, about five or six wraps should be enough for the job.
Step 5: When done, simply grip the tape tight and give it a strong tug. Simply smooth out the remaining loose tape onto your pipe, and you are done.
While using thread seal tape is great in most cases, unfortunately there are some occasions where it is not the ideal tool for the job. Some pipes have wide threads, which causes water to dribble through. In other instances, the opposite problem can exist, where the pipe will not give you enough room to properly apply the tape. Also, the threads of the pipe you are trying to seal may have suffered some damage or wear and tear, which would make it very difficult for thread seal tape to create an air- or water-tight seal.
I used a ton ton ton of teflon tape on these things and they still leaked. What can I do? All the fittings are Brass and screw together type.
How do I seal these???? Did you tighten them with a wrench?? I can't beleive they are leaking Pay attention to the direction you wind the tape too. If you apply it counter to the direction of the threads I won't solder these either. While it is possible Thanks guys, Puppet, You may have a point, I did use quite a lot of Teflone tape, but I can't imagine that that would be the problem.
I didn't even know there was such a thing. I guess I'll try that next. BTW, it is OK if this is a permanent thing. Any other suggestions???? Teflon tape should have been sufficient, assuming you tightened all the fittings with a wrench. Can't imagine you'd want anything that "hardens".
The white teflon stuff is good. As is the older regular grey stuff. When using tape, three wraps should do it. Something's wrong if it doesn't. You'll have leaks if you under, or over, tighten. Everything is NPT? You didn't happen to get hold of some straight thread stuff did you? I like plastic. As a last resort you could always use J. If that doesn't work, I'd try soldering it. Well, I guess that might be the problem, though I really have no clue.
I used a ton of the teflon tape, and I mean a ton Half the reason I did this was so that I could have all the stopcocks in the same direction. It could be a problem if they weren't. Edit: And BTW, it wasn't like just one connection was leaking. There were lots of connections leaking I am stumped and serious thinking of just going for plastic fittings. Guys, please realize that I am an idiot on this subject and many others.
I wanted to get all the valves to have the same orientation, but their may in lie the problem. All the connections are very tight, but they are tighted to the point that they are all in the same direction.
Could this be the problem Maybe I'll just scrap every thing and go to plastic and PVC glue Stop spending money on hardware, and go buy a book about home plumbing. You'll get it not to leak, and learn stuff that will be handy around the house too. Good luck! Wow, I just asked if I would have the exact same problem with screw type fittings over on Procooling. I don't see why you can't solder it, but you really shouldn't have to.
Assuming all the threads are the same I doubt you would be able to screw at all if they weren't , you should be fine. Hell my house uses a few of these types of fittings and it doesn't leak.
I'd take it apart and redo the tape. Just make sure to cover anything and tighten it as much as possible. Perhaps I will use solder on mine after all. Just wondering, how heavy is yours? All the valves I looked at were so heavy I'd need external support for just one, let alone 3! Minewhile PVC is so light. Also did you use ball valves?
With all that tape, the fittings can't be threaded into each other far enough to form a seal. Ya, too much tape. You'd have to have high quality fittings to get by with one layer though. Getting the valve to line up shouldn't be a problem. Elbows and tees have to oriented the right way too so it's done all the time. The only thing you can do is make it go on around. Just don't go too far and then try to back it off.
