LOCTITE 55 Pipe Thread Sealant, Non-Curing Cord, White, 1x50m

Reviewed May 2023: Bought this after a recommendation from a YouTube channel on the best ways to ensure compression joints are totally sealed and he was using this stuff. Although regular PTFE is pretty cheap for a roll, its usually for 12 metres or so. (thats still a lot of pipes that can be sealed!). This loctite cord is 50 metres, I'm thinking this will probably last me the rest of my lifetime if I don't loose it. This is cord, not flat tape.. one lesson as that its not necessary to have tape flat (how much time and frustration has been spent in the past!). In the case of compression fittings, its a case of winding about 7 turns on the pipe below the olive (once the olive is in place from an initial tightening). Then, when tightening up, the cord is compressed under the screw fitting and against the olive. Its very tidy, with no cord/tape on show, and I had a 100% first time success rate of zero leaks! The casing has a cutter, which is helpful because it means you can cut it off one handed, and its red in colour which helps when trying to find it after putting it down. I'd buy this again if I run out or loose this reel.

I wish I had discovered this thread sealing cord earlier. It works very well and is easy to use. Unfortunately, the sticker Amazon places for their stock code obscures the usage guidance, so be careful to refer to the website if you can't peel it off successfully. The key is using the correct number of turns related to your pipe diameter, and in winding each turn across the thread rather than within the thread. I just knew it was going to work as I tightened each joint - a smooth resistance, which became higher as the end of the tightening approached. I particularly like the way a sealed joint can be re- orientated (for example, to align a tap) after assembly without losing watertightness. If you need to remove a joint, it's easier to clean the threads of this cord compared to PTFE tape, or sealing gunk. It's an updated version of the old plumbers' standby, hemp fibre. You get a lot of cord in the dispenser for the money, so I consider it decent value for money. Switch to this and you'll never go back to PTFE tape.

This works on my outside tap tried the liquid sealer but it dripped this stuff fixed the dripping

Cant fault the stuff, works great and hasnt given me any issues so far

This stuff is great. So simple to use. You can back off the thread on a tap (for example for alignment) and still maintain a water tight seal.

Seals the joint if you don’t need to undo later

You have got to try it! 12 joints No leaks what so ever! Brilliant.

As described fast delivery thanks

Très facile d'utilisation et très efficace

Works well. Hand tightened a shower head with just the rubber washer - leaked, a lot. A wrapping of this product - sealed up tight!

As advertised

Utilizzato su un tubo di carico acqua di una lavatrice che dopo svariati tentativi continuava a perdere, ha magicamente risolto il problema. Raccomando di passare il filo attorno alla filettatura da proteggere incrociandolo piu' volte. Acquisto raccomandato.

Ich hatte es bestellt, da es für fast jede Leitung geeignet sein soll. Alles was ich bisher damit abgedichtet habe, hällt und tropft nicht. Ob Wasserleitung im Keller oder Anschlüsse am Pool - Ich finde das es leicht zu verarbeiten ist und prima hällt. Die Schneide zum ablängen ist aus meiner Sicht echt praktisch. Kein Reißen oder Herumgefummel um den Anfang von dem Dichtband zu finden. Ich habe auch das Gefühl, das man von diesen Faden weniger verbraucht im Vergleich zu herkömmlichen Teflonstreifen.
