Rectorseal 25790 1-3/4-Ounce Tube No.5 Pipe Thread Sealant

Seals well and a great size for small jobs.

Bought a leaky air hose for a compressor. It just needed thread sealer, and this stuff sealed the leaks completely.

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.

I use this on galvanised pipe and copper lines to propane appliances.I much prefer if over sealant tape.Its my go to in my plumbing fittings bag.Haven't had any leaks yet.

cap was off is packaging, but the tube was sealed all is great

Excellent ease of use and storage. Perfect for natural gas pipe fittings. I never have had a leak problem.

This is so much better than the Teflon paste sealer. It is very consistent, goes on smoothly and seals very well.

Good thread sealant. It worked well on some air-tool and air-line fittings I needed to replace.
