What is a Plumbing Sealant?
Plumbing sealants are designed to create a seal where pipes or plumbing devices join. These sealants come in handy when installing new pipes, because they help to cover tiny crevices between threads that could lead to leaks and damage to the surrounding area.
Types of plumbing sealants
Plumbers typically use three main types of plumbing sealants:
PTFE Tape Tapes are common to use for home plumbing systems, and are an easy and effective way to cover crevices (plus, they’re easy to remove).
Pipe Dope Pipe dope refers to chemicals used to seal pipes together, and can effectively seal up crevices and leaks. Over time, this type of sealant can shrink up, so you’ll eventually need to replace it.
Anaerobic Resin Compounds This is a mixture of substances that create a clay-like compound used to seal pipes and crevices. These resin compounds are considered a long-term solution, because unlike pipe dope, compounds do not shrink up.
What to Consider When Using a Plumbing Sealant
Different kinds of plumbing sealants are designed for different situations. If you’re planning on using a plumbing sealant, consider these factors when you’re making your choice:
Temperature of the room
Temperature of the liquid or gas flowing through the pipe
What’s flowing through the pipe (liquid or gas)
Amount of pressure held by the sealant
Easily removable versus a long-term solution
Once you have a good idea of the elements at play, you can compare types and brands of sealants.
