Its more important to wind it on the right way than to use a lot,

Further to Tom’s excellent video, there’s a few other products that’s used on Radiator valve tails;
Loctite 55 or PTFE string. This is wound on as instructed, but you can turn the fitting back, to change it’s orientation, without it leaking.
Liquid PTFE or Anaerobic glue. This basically glues the Male & female threads together. It sets up on the threads when there’s no air in the joint.
Old Skool hemp & boss white. Rapping the Male thread with hemp & covering with Boss White.
Pros & Cons to all👍

Or if your stuck, garden twine and a touch of gloss paint/ nail varnish.

Cheers Dick! I was going to boss white, or similar, my outside tap, (or cut a bit of thread off), as it needs to be backed off 3/4 a turn. Thread it is!

Loctite 55 or PTFE string is ideal for something like an outside tap. Ideal to aline something. This stuff is good & a lot cheaper that the Loctite 55 www.ebay.co.uk/itm/323685921034 |

Is there any cheap alternative to the liquid ptfe? Many thanks Here’s the video AJ, though the link I posted is far cheaper. Liquid PTFE or Loctite 577 is the Anaerobic glue. Amazing stuff! But goes rock hard in the joint, the only way you can remove it is with heating the joint. You may recall Tom’s video of gluing the EF fittings with this stuff?? |

Mind that Loctite 55 is real good stuff and well worth the uplift in price for tricky jobs. |

dick do you have alink for a cheaper version of loctite 577 Screwfix Liquid PTFE is the same stuff. As said, it’s all anaerobic glue - but various strengths. All these jointing methods have Pros & Cons. |
