Application of sealant products on threads.

Thread sealant products prevent leaks, avoid pressure losses, and extend the lifespan of equipment.

What is a sealant product?

A sealant product is a substance used to prevent the leakage of liquids or gases through fittings or assembled parts.
Applied to contacting surfaces to create a watertight barrier resistant to high pressures and temperatures, sealant products are used in a variety of industrial and domestic applications to ensure the integrity of systems and equipment, preventing fluid losses and material damage.

Why apply this product?

This helps prevent leaks of fluids or gases, which can lead to pressure loss, decreased system efficiency, and material damage.
Threads can have imperfections or gaps between the threads that allow liquids or gases to escape. By applying a sealant product on the threads, it’s possible to fill these gaps and prevent leaks.

What can cause leaks?

Poorly machined or damaged threading.

Imperfections or irregularities in the threads can hinder proper sealing.

Insufficient or excessive tightening.

If the tension of the assembled parts is not sufficient, the threads won’t be tight enough and leaks can occur. Conversely, excessive tension can damage the threads and lead to leaks.


Threads can corrode over time, which can lead to gaps between the threads and leaks. Vibrations can also loosen assembled parts and cause leaks.

It's important to choose a suitable sealant product based on the characteristics of the parts being assembled, as well as the stresses the assembly will undergo
