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

Turns out my older house, being at the bottom of a steep hill, has very high water pressure (120 psi or so, should be 60...eventually solved by putting in a pressure regulator). But, Before I finally figured that out, my DIY plumbing jobs involving brass threaded plumbing fixtures invariably led to small leaks that simply would not go away. Teflon tape would not work, nor several brands of pipe dope. I finally tried Loctite 55 pipe sealing thread, following advice on how to apply from youtube. This stuff works, never a problem with leaking threaded fittings from then on. After discovery of how well Loctite 55 works, I then found out about the high water pressure (yea, it should have obvious to check that earlier...my bad). But, still happy w the Loctite 55.

Been using this for 15 years, VERY hard to find in South Africa and costs a fortune here. Cannot even find this big roll here only small rolls. My last roll this size lasted me some 10 years so I guess Im covered for another decade or more.

One is Loctite 55; the other is regular plumbers tape I twisted up. I usually spend time trying to not twist my plumbers tape. The biggest difference is that the Loctite 55 comes out a bit flat, so you cant twist the regular stuff too tightly if you want to match the Loctite 55. I tried the Loctite 55 on a new faucet I am installing, and it did not go well at all. It is really hard to get it just into the threads, but if you dont you cant tighten the bolt; it jams. I ended up removing the Loctite 55 and using regular plumbers tape. BTW, the Loctite 55 is on the right in the photo.

Used this on a couple of pipe fittings with some additional paste. And have not had any leaks. Better results than I have had in the past with just paste or tape.
