Loctite 55 Pipe Sealing Thread Cord for Water and Gas Leak Fix - Size 150m

seals better then teflon tape and allows for some re-positioning without leaking

I had a leak in a 2 pvc supply line when I added a filter. The leak was in the threads to the filter. I had done and redone it twice with no luck stopping the leak. Then I found this sealing cord online. My gut reaction when I got it was to use more than instructed. It said 12-25 rotations for 2. So I figured that 35 would be even better. What I quickly learned was this cord somehow gets heavier as you tighten it. It became so tight after only half way on that I couldnt tighten it any more. So I started over with new cord. This time I used the max rotations of 25. I got it on, but like before it got so difficult to tighten that I barely got past half way. I figured whatever this cord is doing in the threads I could not imagine how any water could slip through. And none has. I guess like the videos show, you dont have to completely cover all the threads. I will add that I could not find that much information about thread sealing cord. Maybe I just didnt look hard enough. But I could not find much. But this stuff works! It doesnt seem to shred like Teflon tape does. It gets very fibery and stringy. Yet tough.

Stopped a leak with a new water Bibb. Fantastic stuff.

Works well with British style (straight, not tapered) pipe fittings.
