Loctite 577 can be used on anything up to 3” (gas reg stops you at 2” anyway but can be used on water obvs); but if used on above 1 1/2” you’ll need to put heat on it to get it apart. I spoke to their staff as needed some info when doing a boiler room 👍

The Loctite 55 is totally PTFE free, dunno what the white lubricant on / in it is but not PTFE. I used to do work for Imperial Tobacco or John Players Cigarettes as it once was, they had a blanket ban on PTFE use anywhere in the factory as PTFE gives off toxic fumes if it is burned with a flame! You can imagine if it got into a cigarette can't you...... Loctite 55 was approved therefore, I would imagine Loctite 577 would be fine also. Imperial Tobacco closed down here in Nottingham and is a demolition site at the moment 😳

When I use ptfe tape on a parallel threaded fitting I make a cone of the tape. Less on the end more to the back. Starting at the back of the thread I go to the front / end of thread. When I'm done, usually about 15 revolutions, the end of the thread has the least tape applied and the back end of the thread has the most / thickest tape applied. I always run my finger nail around the thread pushing the tape into the thread the full length of the threads so that there is more tape in the thread ,less tape can be pushed back off the thread.

Del the Loctite 577 is an Aerobic Glue, it basically glues the threads together in the absence of oxygen. Amazing stuff, there’s various grades of this Glue & is used depending on the application. Aerobic glue can also be used to glue copper tube & End Feed fittings; simply by using Emery Cloth or both surfaces. Screwfix sell a Liquid PTFE that’s basically Aerobic Glue, a lot cheaper than the Loctite 577. HTH

I’m a Tennant connecting a gas line for a furnace. My apartments main gas line is 1/2” all I have is 3/8 pvc, my buddy says it’s better to use steel and pvc is not compatible for gas. I don’t see the difference 🙄 My question is the 3/8 is too small to fit the nipple. Is it acceptable using the pipe tape to build up the smaller plastic pipe and thread it on the larger steel gas pipe? It gas checks with no leaks and plastic won’t spark. So far the heater has been phenomenal. If you want a recommendation for a wall heater pm me. Peace.

You must use the correct products for potable water. Boss green and jet blue are good with potable water. You would only need some kind of binder if the fittings are over 3/4 and you must use the binder which is for potable water. Some of the manufacturers of the paste say reinforced fibre is needed over 1/2 but I have never used it on 3/4 and had a problem.

You succeeded to screw only half of the pipes because the tape at the end of the screw is too much. Sealing is made inside the pipes, therefore be sure to use almost all the filet. Another 2 things: 1. First it is worth rolling the tape in a thread and filling, in one carefully run, clockwise, the inside of the screw. Then wrap the tape over, as a tape, like you did. 2. Before screwing the pipes, LUBRICATE the inside pipe as well as the pipe with tape. This ensures the tape will enter as much as possible undamaged between screws and not get out and agglomerate outside - as it is visible in your video. Loctite 55 thread is better, with the same steps

Random/Negligent way of wrapping Loctite 55 thread is a big NO. The random wrapping and diagonals are completely wrong. The first wrap should not cross the screw peakss at all and the direction is against the rotation of pipes (the thread is rolled clockwise). Then, if possible, another run, or as many as needed to obtain a little and CONSTANT opposition while rotating. If in the video that negligent wrapping works, it is simply luck. Do not play gambles with gas or water.

There is no difference between the two PTFE tapes. We routinely use the “non gas” tape on threaded gas fittings at 300 bar+ offshore. All the PTFE Is sealing the spiral leak path between the root and peak of the thread. PTFE should only be used on tapered threads. It’s use in domestic plumbing is quite limited because almost all are parallel.
