Threadlockers and Sealants
Threadlockers and Sealants
Threadlocking adhesives and sealants are specified throughout this
manual by a notation of “S” plus a number (S#) and should be used
where indicated. Threadlocking compounds normally break down at
temperatures above 175°C (350°F). If a screw or bolt is hard to
remove, heat it using a small propane torch to break down the sealant.
When applying sealants, follow instructions on container. The sealants
listed are recommended for use on Wacker equipment.
