Many do-it-yourselfers know how to seal threads with winding, linen. Surely you, the reader, are able to do this with ease. And if someone does not know how, then he previously wrote for you how to do it. There is a link at the bottom of the article, Learning is light.
With normal thread winding, flax is wound in a clockwise direction, with an interference fit. At the end of this action, the thread is coated with a sealing paste.
But it turns out there is one peculiarity, when packing threads... This wisdom, at the beginning of my career, not surprisingly, was taught by a gas welder, my work partner. He had to suffer with me then, I was young, green, inexperienced. He passed on a lot of skills. Now I remember him with a kind word, one thing was a real mentor.
So, he showed and taught me green how to properly wind flax on a thread. Quite often, the first thread of his thread was not closed with flax.
He did this so that the threaded part immediately entered the hook with the mating fitting or pipe, the winding did not interfere. There were a lot of black pipes and details at that time. And quite often, carvings were made "handicraft" "on the knee" by a local half-drunk turner. He will not finish the thread, then he will sink. Therefore, so as not to suffer when joining the threads, the first turn was not compacted.
It is especially important not to rewind the start of the thread when installing valves under pressure.
This method of packing the threads with flax does not in any way affect the tightness of the connection, but it greatly facilitates the installation of threads in certain and difficult cases.
Like the Mentor Welder for the shared experience. Thank you!
