Review: Less hassle! High quality tape. - I've heard about this tape for quite sometime and figured I'd give it a try. I would make sure if you're planning to do a lot of thread wrapping, get more than one. I was redoing all my sprinkler adapters and luckily, one whole tape was just enough but even for the higher price, I do feel it's worth it. One thing that I always hated was trying to keep the tape flat with the traditional PTFE tape. It's too thin and breaks easily while this blue tape I'd say is twice if not three times as thick so it doesn't easily fold. Since it's thicker, I only wrapped it twice. Just make sure to wrap them in the correct direction as you'll quickly find out you wrapped them in the wrong direction being thick. Most of the pipe diameter was between 5/8"-1" so these worked out perfect. A bit too wide for smaller threads but it still worked out well. Overall, I'm very satisfied and will buy some more. Where I'll keep the traditional PTFE is for areas I won't be wrapping often and can take my time.
Review: Much Better Than the Average Thread Tape - I had a shower valve cap with a slow drip. I tried the white teflon tape and it slowed down, but still leaked. I read about the blue Monster tape on a Reddit thread and decided to give it a try before a $200 plumbing house call. I wrapped the threads about four times in the direction that the cap would screw on. The cap got a great seal and I haven’t seen a single drip since. I am a DIY homeowner and amateur plumber at best. In the photo, you can see I put a shallow lid underneath the valve for 48 hour test. No drips. This stuff is highly recommended for a good reason. It saved me a lot of money, and I always want to have some of this on hand.
