RectorSeal No. 5 25790 Pipe Thread Sealant, Lubricates & Protects Threads, Soft Setting, Slow Drying, & Permits Easy Breakout and Contains No Other Metals, 1.75 oz

I use this thread sealant for my fuel cut off valves that I installed on my aqua hot heater on my RV. No leaks works really good. Great product.

Works well maybe to well so just saying it may say rector seal but don’t use this on your rectum that’s not a place we need sealed on our selves use only for your plumbing and gas needs.

Needed to wait an hour for curing time, otherwise after a few minutes it didn't create a strong enough seal on the threads to stop the slow leak. I wish they just stated this in the instructions, I had to find out searching google. They want to sell it as if it works immediately, but I don't see that being realistic based on my experience.

Price is unbeatable. Comes with plenty for what I needed it for which was a Blackstone grill. the color also makes a very easy to see. No issues with application.

Excellent stuff. Not for use on PVC or CPVC. This is good on brass gas lines, etc. If looking for a more general purpose, go with the white tube, not the yellow one. I tape first, then place a coat of this on top of the tape.

I installed a bidet on my toilet, and I'm a 62-year-old grandmother. When I first installed it the tape that you wrap around the pipe thread did not seal the water. I read reviews on this sealer in this tube, and all the reviews were good. So I ordered it and I ordered a new line from the tank to the water outlet. And all I did was put the seller around the threading and I waited an hour before turning the water back on. It sealed it. I am so impressed by the sealer, that I had to explain the process of what I went through, installing of the day by myself. There are no leaks and it has been several days. I am very happy with this seller and will recommend it to everyone that I know.

My well pressure tank started showing signs that it was failing. The well pump would cycle frequently, build up a lot of pressure and then drop quickly. I didn't want to burn out the pump or create a water line leak. I purchased the same Well-X-Trol unit, a Boshart tee kit and associated fittings and reducers. I initially only used the typical white Teflon tape around the threads. I did this even seeing that the old fittings had sealant around them. Sure enough, I encountered some small leaks. All but one sealed themselves over time. The leak that remained was at the tank and tee junction. It wasn't a gross leak, so I figured I would get to it when I had time. As it turns out, a pinhole leak in the copper piping forced me down that road. I had shut all the water off and the next morning the entire pressure tank was empty. So along with fixing the water line leak, I opted to redo all the fittings and connections on the pressure tank and tee. I searched plumbing forums, and it was recommended to use a better tape and/or a sealant. There is much debate as to whether to use one or both, but I opted to use both. I used Megatape and Rector Seal # 5 the second time around. I wrapped the tape around the threads in such a manner that it was always in the clockwise orientation when being screwed into a fitting. This orientation helps to ensure the tape doesn't unravel as fittings are being mated. I went around at least four times for most fittings, the exception being at the tank and tee junction, which I wrapped five to six times. I made sure the tape was fairly tight around the threads as it was being applied, went over it a couple times with my fingers and then added Rector Seal # 5 over the tape. The sealant filled in the thread groove nicely even served as a lubricant during installation. This allowed me to at least get one to two full turns on each fitting. Long story short, the second time around worked. In the future, I will follow the same procedure on any plumbing job that has similar fittings.

This stuff is awesome. For propane or water, Seals on the first try every time!

Used this for connecting our gas stove. Followed the directions and have had no issues. Great product.

We use this for sealing almost everything! Worked well on our trip to Alaska and back.

Good product. Great Customer service! Highly recommended.

I needed to seal a gas line in our house after a fitting change and I won't cut corners where my family's safety is concerned . Ordered it up, used it as directed, tested for leaks and all was good! there's not much more I could tell you about it other than it effectively sealed the pipe joint where it counts! Recommended!
