Review: Seals threads like it should - Works great. Seals like it should. Easy to apply, and enough for lots of fittings. I got tired of finding shreds of Teflon tape clogging orifices, so went back to paste sealant. It doesn't dry out, and allows some adjustment of the fitting after assembly, while lubing and sealing the threads.

great product seals pvc thread no leaks

### ⭐⭐⭐⭐⭐ Incredible
*by J***R on March 14, 2023*

I have been in the water system business for 18 years and have used Teflon tape, Megaloc, and StickTite paste. I have found Megaloc to be the best. It’s always been my sure thing with Teflon tape on difficult joints, but I finally ran into one that my tried and true failed me for the first time. It was a 1-1/4” size and I was screwing brass into a plastic filter housing. I tried 3 times with Megaloc and a couple times with StickTite plumber paste and even gave it time to dry. To my surprise each attempt failed. I have never used True Blue since I have been loyal to Megaloc since it’s never failed me until now. I ordered this stuff and gave it a try. It worked on the first attempt. I put True Blue in the threads and on the threads of the male and let it try for almost 24 hrs. No leaks several days later. I’m convinced and will be using it from here on.
