Thread Sealing
� Prevents leaks
� Single component – quick and easy to apply
� Can be used on any size pipe fitting
� Prevents corrosion and galling in threads
Loctite® liquid thread sealants seal and secure metal pipes and fittings, filling the space between
threaded metal parts, and hardening to prevent leakage. Designed for low and high pressure
applications, liquid thread sealants seal instantly for low pressure testing. When fully cured, they
seal to the burst strength of most piping systems. The new innovative semi-solid stick formula
offers added convenience and portability for general maintenance and hard-to-reach applications.
