Thread Sealants

Showing all 18 results

Thread sealants are products used to prevent fluid and gas leaks in a threaded pipe connection. They are easy to apply and cure quickly.

They work by filling the gaps between the male and female threaded connections. They also function as a lubricant as the threads are put together. Sealants cure in the absence of air. After hardening, they form a tough thermoset plastic, providing a leak-free seal.

Thread sealants typically resist temperatures between -55° C to +150° C. This range is ideal for most hydraulic and pneumatic lines.

Types of thread sealants

They are available in a wide range of viscosities, strengths, and cure speeds. Each product is designed to meet your specific application requirements.

Sealants come in three forms:

  • Liquid (low or high viscosity): Low viscosity sealant is suited for pipe threads of up to 2 cm diameter. It is also a good choice for pipes with fine threads, so that the liquid can quickly fill in all the gaps. High viscosity sealant is better suited to pipe joints with coarse threads.
  • Paste (also available on stick dispensers): Sealing paste will perform better on pipes of 5 to 7,5 cm diameter.
  • Tape and cords: This type of sealant is suited for larger pipe joints of up to 10 cm. Sealing cord is especially recommended for plastic pipes.
