How to Choose the Right Industrial Thread Sealant

A thread sealant primarily consists of an anaerobic glue that seals the gaps and cures to create a strong thermoset plastic coating around the leak.

Leaks are a frequent occurrence in systems with threaded fluid flow. Although ordinary thread tape or paste can make quick repairs, the results are often uneven and inadequate sealing. Consequently, external variables such as shock loads and dynamic pressures often cause the threaded connections to fail unexpectedly.

As a result, thread sealants (pipe thread sealants) are more dependable and convenient alternatives. This is one of the main reasons thread sealants are frequently suggested for fluid power systems and industrial facilities.

Insight

Every year, leakage results in the loss of over a billion gallons of industrial fluids. Aside from the monetary worth of lost gases and fluids, leaks have adverse effects on toxicity, safety, emissions, contamination, and people, as well as the extra costs associated with finding, diagnosing, and fixing leaks in pipe systems, among other factors. There are some measures you can take to increase the lifespan of industrial equipment.

The primary source of any leakage can be traced back to the space between the male and female pipe joints threads. The pipe threads are often inaccurate and lack a defined torque for installation, although consistent fittings are required by law. This results in thread damage. 

For a long time, PTFE tape was the go-to remedy for leaks. PTFE, or polytetrafluoroethylene, has been one of the often-used industrial sealing solutions because of its various characteristics making it an excellent choice for these applications. Also, PTFE can be used in different ways to provide a fantastic solution to problems raised in industry and households.

However, when tightened, they shred and form leak pathways, reducing the dependability of the seal. A thread sealant that is based on anaerobic technology is a better option in this situation.

How Industrial Thread Sealant Prevents Leaks?

A thread sealant is primarily an anaerobic glue that comes in liquid or paste form. When applied between threaded metal components or surfaces, the compound fills the gaps and cures in the absence of air to create a strong thermoset plastic coating around the leak.

Consequently, you get a high-pressure seal immediately, which often seals the burst pressure of the pipe system. Thus, thread sealants prevent leaks by forming a tight seal, even under extreme temperature variations or vibrations. Thread sealants have developed into a powerful solution for a variety of industrial applications.

However, keep in mind that the seal’s dependability is strongly related to the type and quality of the glue utilized. Therefore, while choosing the sealant, make sure to choose from a reputable business. 

The Process of Selection:

How do you choose a thread sealant that meets your project’s requirements?

Thread sealants are available in various types, each of which is designed to meet the specific requirements of a particular application. As a result, the whole procedure may seem complicated, but instead, it is very straightforward.

If you want to select the best product for your sealing requirements, begin by answering the following questions:

  • What kind of substrate are you trying to seal?
  • What is the largest thread size?
  • What is the required temperature resistance?

As you review the questions above, you may estimate the technical specifications for your repair and choose the best kind of thread sealant for the task. Nonetheless, you must always depend on a reputable company to get high-quality products.

How Do You Choose the Most Suitable Thread Sealant?

You may choose the suitable thread sealant by clarifying the following queries!

1. Is the Pipe Metal or Plastic?

Anaerobic liquid thread sealants may be used to seal metal threads efficiently. However, the consistency of the paste to be used will also vary depending on whether the metal is copper, brass, steel, or aluminum. If you need to seal plastic threads, go for instant-seal thread sealing cords.

2. Are the Pipe Joint’s Threads Coarse or Fine?

Coarse threaded pipe joints have lower threads per axial distance. That is why we recommend using high viscosity thread sealants. However, delicate threaded pipe joints have more threads per axial distance. In that case, we suggest using low viscosity thread sealants, as the liquid fills up the gaps rapidly.

3. What is the Diameter?

It is better to use low viscosity thread sealants for pipe threads up to 34 inches in diameter. Thread sealing pastes work best if the pipe threads are between 2 and 3 inches in diameter. Use thread sealing cords for larger pipe junction sizes up to 4 inches.

4. What Is the Required Temperature Resistance?

Thread sealants based on anaerobic technology are usually resistant to temperatures ranging from -55 C to +150 C, making them suitable for most hydraulic and pneumatic lines. Certain thread sealants may also withstand greater temperatures, depending on the application.

5. Simple Hacks for the Perfect Seal:

Here are some simple tips for creating the perfect seal.

There are many kinds of sealants available. So, you should consider the surfaces and materials you are using before choosing a sealant. Keep in mind that some are ideal for indoor or outdoor use, while others can be utilized in various environments. For example, kitchen faucet leaks will be different from exterior pipe leaks. Also, some of it will survive all weather conditions while others will not, so do your research first.

1. Straws for Smaller Spaces

When applying sealant, you may discover that certain areas are too small for a conventional caulk gun. You can use a straw in such places. You simply need to slice the straw at a 45-degree angle. Then,  tape the spout end and finish sealing, as usual, using a more accurate tool.

2. Screws can Unclog a Blocked Tube

If you have not wiped off the extra sealant, it may quickly get blocked. In that case, use screws with a rougher head to penetrate the cured sealant, clearing the spout and preventing product waste.

3. Remove Residue with Rubbing Alcohol

Cleaning off the residue with rubbing alcohol is one method. It dries quickly, so you can start sealing again in no time.

Conclusion

Replacing PTFE tape and using a liquid thread sealer can be challenging. Because getting familiar with the product names and selection criteria may take some time. However, we hope that the approach outlined above assists you in selecting the appropriate thread sealant for your application.
