Thread / Pipe Sealant

About the product

The Hitlock products used for pipe sealing need to be particularly reliable in order to prevent the escape of gases and fluids.

Anyone who needs professional products to seal pipes, joints and other pipe sealing applications will find the perfect solution for every job and material with Hitlock.

Characteristics of an anaerobic seal with Hitlock

Anaerobic materials for pipe sealing harden to insoluble plastic fillings and provide protection from leaks. With this type of pipe sealing, anaerobic single-component fillers fill the microscopically small gaps between the interlocking threads and polymerise to a tough solid on contact with metal when air is excluded.


Hitlock offers products especially for use with metal and stainless steel, providing a slow-curing seal for readjustment of the connections and a medium strength pipe sealing.
