What Is a Pipe Thread Sealant?

The plumbing and heating supplies industry is worth over $71 billion. Plumbing supplies include pipes, valves, and tanks. Substances like pipe thread sealants are essential for these supplies to work.

A thread sealant is a material that fills the gaps in threaded pipe connections. This sealant prevents fluids from leaking out of the pipes. It can also help lubricate the threads and make assembly more efficient.

Pipe thread sealants come in two varieties. The first kind is paste sealants that the user can apply using a brush or a finger. The user can apply the paste sealant direct to the male and female threads.

The paste sealants are a mixture of different substances. The mix includes rosin, ethanol, and vegetable oil. It’s ideal for making pipes air-tight.

Another type of pipe thread sealant is tapes. These tape thread sealants offer a mess-free application. It works by wrapping and pressing the sealant tape around the pipe threads.

Some tape sealants come in different widths, thicknesses, and densities. These varying features allow plumbers to choose the perfect size for the pipes. These tapes act as a lubricant to lessen resistance when disconnecting the joints.

When looking for tape sealants, you may notice that they come in different colors. These colors state their purpose.

White tapes are for home plumbing repairs. Red tape sealants are for larger pipe joints. Yellow tapes are ideal for air-tight pipes on gas lines.

Pipes that carry oxygen use green tapes because they are an oil-free option.

Choosing a Pipe Sealant

Choosing the ideal pipe sealant can help you prevent leaks. The market offers different options that will suit your needs. Consider the following product features when choosing a pipe thread sealant.

Environmental Condition

The first factor to consider is the environmental conditions of the pipes. It is crucial to choose a sealant that can handle extreme temperatures. These temperatures can cause the pipe sealant to crack and cause leaks.


Pressure is another factor to consider when choosing a sealant for the pipes. High-pressure leaks can happen if the pipe sealant can’t handle the pipe pressure. Choose a pipe sealant that can withstand 10,000 psi for liquid pressure and 3,000 psi for gas pressure.

Pipe Material

You should also consider the pipe material when choosing the pipe sealant.

For metal pipes, PTFE and anaerobic resin pipe thread sealers work best. These synthetic thread sealants are flexible and easy to apply to all metal pipe threads.

PTFE or Teflon tapes come in different varieties suited for air, water, and gas pipes. They are suitable for lubricating pipe threads. Its slippery property also makes it ideal in preventing friction when fixing pipes.

Fix Pipe With Paste Sealants

After choosing the appropriate sealant for the job, you can start working on the project. The first step is to gather all the parts you want to seal or connect. It’s best to wear gloves to protect your hands from the chemicals.

The next step is to clean the external and internal surfaces of the pipes. This step rids the parts of oil and dirt that might affect the sealing process. Dry all the pipe parts before working on the next step.

One thing to consider is the type of pipe you will be repairing. The material should be compatible with the pipe sealant you will use.

If you plan on working with metal pipes, you can spray an activator on its surface. This step prepares the metal pipes for bonding.

For paste sealants, apply a bead amount around the male thread. You can then insert the male thread part into the female thread part. Screw the two pieces together and make sure to fill any gaps.

Next, tighten both threads using the appropriate tools. You can use a pipe wrench for this part. The last part is cleaning up any excess pipe sealant before drying.

Wash your hands after working with a paste sealant for the pipes.

Seal Pipe With Tape Sealant

Tape sealants are ideal for preventing pipes from sticking. This feature comes in handy when you want to disassemble the pipe joints. Choose a size that fits well with the metal pipes you will be sealing.

After cleaning the pipes, place the tape on the second thread from the pipe’s end. Hold the ends in place with your finger or thumb. The Teflon tape should be flat over the pipe threads.

Next, wrap the tape around the pipe. Wrap it in the opposite direction of where you will turn the metal pipes. Be sure to maintain tensions to keep the tape from bunching.

Wrap the pipe about four to six times, then break the tape. You can then smooth the loose end over the threads. You can now screw the two metal pipes together.

Remember that tape pipe sealants don’t need drying. These sealants are also not adhesives. They can make disassembling pipes easier.

Its hydrophobic properties make it ideal for fixing water pipes. You can use it to seal water pipes in the shower and the sink.
