La-Co42019 Slic-Tite Premium Thread Sealant Paste with PTFE, -50 to 500 Degree F Temperature, 1/2 pt Jar with Brush in Cap , White

This stuff works great for ceiling pipe threads. I like to put this on my threads and then a little bit of Teflon tape over top of it or vice versa. Definitely worth the money. Great seal, easy to use, and easily removed with a towel.

THIS STUFF IS THE BOMB! Stopped an engine oil pressure sensor leak that the "name brands" failed to seal!!!! No need for long cure times either; just apply to threads, torque it down, and your good to go!! THIS IS NOW MY GO-TO THREAD SEALER!!

Very Good Quality

Great stuff works good where their are oils that can get on it. And it's good to 500 degrees

Does a good job on bad joints

The only reason I bought this brand was, I was gonna put in a tankless water heater, but needed to put in a large larger gas meter. So the gas company came out and put in the new meter and I was a little bit shocked. They used this product rather than Teflon tape… good enough for me, so use this product on 35 feet of 1 inch gas line for my tankless water heater- no leaks with 11 psi of pressure.

Just as it should be. Perfect!

I've been using laco for 50 years of my life in the plumbing and gas fitting trade. High end restaurants,it seals the threads and has lubricant abilities which allows the fitting to tighten even better. Best part is years later when undoing fittings they come right apart. If I could give it 10 stars I would. Retired 4 years ago and yep got a bottle in my tool bag. Very easy to use and any excess wipes right off...
