How LOCTITE® Thread Sealants Work - 

Thread sealants prevent leakage of gases and liquids from pipe joints. All such joints are considered to be dynamic due to vibration, changing pressures or changing temperatures. Thread sealing is achieved as the anaerobic compound cures when confined in the absence of air, and between close metal fitting surfaces. Other anaerobic products offered by Henkel include gasket sealants/flange sealantsretaining compounds and threadlockers.

Loctite Thread Sealing Solutions for Industrial Manufacturing

Instantly Seal Fittings & Pipe Threads

Pipe dopes and thread tapes are one way to attempt to seal fittings and pipe threads. It's not the best way -

Thread Sealants or Pipe Dope?
Pipe joints are dynamic: they experience vibration, changing pressures and changing temperatures, all of which put stress on threads and lead to leakage and expensive repairs. Easy to apply Loctite Thread Sealants instantly provide a durable seal between close fitting threads to prevent the costly leakage of gas and liquids, while stopping corrosion and eliminating the problems caused when pipe dopes and tapes shrink and break down over time.

Loctite Thread Sealants: a Better Way!

Better because they are easy to apply and cure instantly to fill the space between threaded metal parts and assure 100% sealing preventing any leakage.

Better because they can prevent corrosion and elimiinate seized assemblies that cause excessive frustration, cost time, and can be dangerous and costly to repair.

Better because they are available in a variety of controlled strengths, are solvent free and will not shrink or crack like solvent based pipe dopes.
