Sealants & Adhesives FAQs

What's the difference between a thread-sealing compound (thread pastes) and an anaerobic thread sealant?

Thread-sealing compounds are usually solvent-based and work by hardening as the solvent evaporates. As solvent-based thread-sealing compounds present a risk of shrinking and cracking over time, they are best for sealing threads in maintenance applications where a permanent rigid bond is not essential.

Anaerobic thread sealants are high-performance sealants that only cure when oxygen is expelled. Anaerobic thread sealants such as Loxeal 58-11 are ideal for sealing permanent fixtures in commercial applications.

When should I use a liquid thread sealant or thread sealing compound instead of thread seal tape?

A liquid thread sealant or thread-sealing compound is recommended when sealing larger-diameter pipelines. For high-strength sealing on permanent structures, it's important to use a high-performance thread sealant such as the Loxeal®58-11. The Loxeal®58-11 is not only AGA-approved for use with gas, it is also WaterMark-approved for use with potable water.

What's the difference between Loxeal 58-11 and 18-10 Thread Sealant?

Whilst Loxeal 18-10 is designed for medium-pressure gas applications, Loxeal 58-11 is designed for high-pressure gas and water applications.
