In today’s market, you have three choices available related to the type of sealant; Teflon tape, pipe dope, and the last choice are anaerobic resin compounds.
Featured with white and nonsticking tape design, it is very easy to use. It is not a thread sealant but for a tape that can clog the thread path. Keep in mind that it does not adhere to the surfaces, just like the real sealant can do.
Using this type is easy, that will never leave any mess. However, it does not adhere. It is not enough to offer a secure seal. Also, the tape is fragile and thin, which means the leak path can be a real matter in the future. Make sure that you only use this tape for standard water pipes or fittings. You should not use it to secure high-pressure systems.
This type of pipe sealant has been there, in the market, for industrial applications. It works with a solvent carrier that can harden once the solvent evaporated. As a result, it adheres to all metal and plastic pipes effectively. Therefore, it can block any leak path.
Since it comes with solvents, the solvent may dissipate and it is possible to shrink over. Here, the condition can cause the dope to pull away from the cracks or the thread walls. In other words, the leaks will develop. You need a pipe dope to solve threaded components by using a spatula or brush.
The good thing about pipe dopes is that it is easy to use and the cost is inexpensive. The composition is also good for all pipe materials, even for plastic. It can harden quickly but seal the path leaks effectively.
On the other hand, the pipe dopes have a solvent that can lose their power by the time, due to heat aging. Leaks may exist when the seal cracks or shrinks. For this reason, you should use pipe dopes for any condition with no pressure or high temperatures. It only can deal with minimal vibration.
Anaerobic Resin Compounds
Unlike pipe dope that contains a solvent, anaerobic resin compounds do not have it. It is why the cured material will never crack or shrink, but the sealing properties will get better even though it gets heat aging. Once it is cured, the compounds will create a strong seal that can deal with temperature, solvents, pressure, and vibration.
The presence of chemical composition makes you should verify it first before using it for plastic fittings and pipes. Even though the compounds cure allows you to use it for immediate uses, but you should observe it for 24 hours before using it for the high-pressure system. It is because anaerobic resins are not easy to clean from gloves and clothing.
Up to now, this sealant is the strongest and the most effective solution available in the market. Ideally, you can use it for any piping system with temperatures of more than 300 F and more than 10,000 psi of pressure.
Finally, you should consider the best pipe thread sealant by thinking of the pipe material, the temperature, the vibration, and the pressure of the piping system. [Source]
