    I have been cursing straight pipe threads since I arrived in Argentina. The most common plumbing system is polyethylene pipe with straight pipe threads. It is sort of sealed by using 10 to 20 wraps of Teflon tape. Hemp used to be used a lot but now not do much. There are also some liquid sealers but I haven't had much luck with them.

    I’ve been using teflon tape with the wrong premise. Thanks for correcting me. Problem is a lot of accessories with straight threads come with Teflon tape which is why I use it everywhere when plumbing. I also use alot tapering the layers. I’m guessing this is wrong? I do this so I can position fittings otherwise the tightness where it won’t leak is in the wrong position.

    • @shermanlarsen7840
      @shermanlarsen7840 3 роки тому +1

      I started repair service in 1986 and discovered the same issue.
      The actual compression size is 5/8 inch, but some manufacturers used a pipe thread instead of a standard compression thread resulting in the issues you noticed.
      If you run into a pipe thread compression fitting, the best bet is to use a puller to remove the pipe thread compression nut and start over with a proper fine thread compression fitting.

    • @1200sbeemer
      @1200sbeemer 3 роки тому

      And never use pipe dope on the threads because this will cause you to possibly over tighten and split the compression nut. In the instructions says you can you can add 1 drop of oil but when the nut becomes hand tight, only tighten the nut half turn more and stop.
      I’ve seen many over tightened and split because of pipe dope on the threads.

    In Europe, Whitworth threads are used for plumbing. Exactly British Standard Pipe.
    BSPP = parallel, BSPT = tapered.
    BSP can be confused with NTP.
    The flanks are 55°, not 60° as with NTP or metric threads.
    There are tapered and straight threads. Straigth threads need a seal as shown.
    Note a 1 inch pipe is approximately 32 millimeters in diameter, not 25.4 mm as usual.
    Even if the mertical system is used in Europe, this old inch standard has remained.

      @Common Sense Realist 577 doesn't harden to the best of my knowledge. Stays kinda 'goey' when I had to remove parts sealed only with this. Works perfectly even on a wet / pressurised system when in a pinch and saves you from faffing around trying to find the beginning of the thread when it's taped with PTFE which is not ideal whilst being sprayed with water at 3 bar...

    threads have an inherent leakage path. the flanks do not create a seal. instead ALL theaded connections have a helical leakage path. You'll strip the threads long before you ever jam them tight enough to prevent leaks. PTFE and dope serve 2 functions. 1: prevents parts from rusting together. 2: fills/clogs the leakage path around the threads.

    I ran into a homeowners brother from far eastern Europe who said they used to fix everything with string and grease.
    In the US we used graphite and string.
    Hemp isn’t far off the mark.
    Anything that will allow the threads to move and tighten and fill gaps might work.
    Do not use ANY of these (except an anti-seize/lubricant) on straight threads that are designed to work with a gasket or a compression fitting.

      To add to this, crests are always at the peak, and roots in the valley, regardless of whether they are external or internal. Your illustration is not entirely correct. Flats exist on both the internal and external forms. Since NPT threads are intended for low pressure, low heat applications, the tolerances on the crests, roots, and flanks (pitch diameters) are quite liberal. When manufactured at one extreme, when the parts are assembled, the crests and roots contact each other and that is the increase in torque that you feel. Further tightening causes these areas to crush until the flanks come into contact. Theoretically, this gives you a "dryseal" fit. At the other extreme, the flanks come together first, and no amount of tightening fills the voids at the crests and roots. This is what the tape, dope, or lubricant is primarily used for. Lubricating and anti-seize are secondary benefits. Since these compounds are inherently weak, they are unacceptable for high pressure/high heat or caustic chemical applications. There are Dryseal threads for this, such as NPTF. I was on the ANSI/ASME standards committees that design and regulate these various forms. Dave

    Hello, I always wonder how you can keep a good seal but still position the threaded object (for example a faucet) in the right position. When you screw it very tight, the faucet may end up on its head, so unscrew it a bit, but that does losen the seal doesn’t it. Thats why hemp is good, it swells up, but the other solutions don’t, so i am confused.

    Here's a Idea for a video and a question. I was sitting here thinking for pvc, pex, and copper pipes, there's alot of screw in pieces now.. So what if someone used Taps and Dies to create their own threads and do their whole pipe system that way rather than soldering, glueing, or crimping? It would be easy to replace a piece ( i mean pex already is easy but gets costly when you need a bunch of fittings.) I would assume thought you have to use NPT, as NPS you would have a hard time figuring out had to add a O ring to pipes especially if your not one of those people that know everything about all things tool and creation wise. It would be interesting and it seems like it would be cheaper than any of the already existing methods.

    I am a retired machinist that cut all kinds of threads on a lathe - Acme, left hand, double lead etc. Now as a handyman plumber I find these video informative. You might have mentioned that sometimes the taper and strait are used together. EXAMPLE: Flexible water heater connectors they are straight pipe female with a rubber seal. They are coupled to a tapered thread male nipple on the water heater. Correct?

    • @Got2Learn

      That is the same in many parts of the world as hemp has different properties that make it a better sealant than PTFE-tape for some applications. Another example would be gas-pipes: In some countries (and parts of the US) it is not allowed to use PTFE-tape to seal the gas-pipes of residential buildings.

  • @jdog4534
    @jdog4534 3 роки тому +2

    Great video! If I may add, we call straight threads a running thread. They are a result of letting the pipe die run down the length of a pipe. ..of course, the leading few threads will be tapered so typically, you would run it on a piece of pipe longer than you need and cut off the tapered threads. Also, if you've ever bought some of that seemingly all thread tubing thats used in lamps and such. ..its basically threaded conduit. I've used it in 3/8" and 1/2" diameters but that's not what they are. You'll never get a nut with NC or NF threads to screw onto them because they're actually 1/8 and 1/4 (respectively) pipe threads. ..and who came up with the sizing on pipe threads? ..maybe there's a schedule of pipe where it all makes sense.
    Oh, ..and don't forget about the British pipe size. If you want to pipe any high pressure air, like from a SCUBA or SCBA tank to use to charge a paintball marker or a PCP air rifle, those fittings are usually in British pipe sizes. They're the same goofy diameters as NPT but the threads are slightly off.

    1:50 between the root and the crest is always space - wouldn't that create a small leak? I guess that's what the PTFE tape is for? I also have a hard time believing that PTFE tape allows you to seat it deeper, as it adds a lot of volume so then you can do less rotations until it's seated. Oil would be an actual lubricant.
