High Temperature Thread Lockers, Pipe Sealants and Liquid Gasket Adhesives

Author: Kurt Harding  

When it comes to thread locking and pipe sealing, one of the most common requirements we find is the need for a thread locker with high temperature resistance.

To make things in this area a little easier, we decided to put together this post which lists just our thread locking, pipe sealing, liquid gasket and cylindrical assembly adhesives that can withstand elevated temperatures.

What counts as a high temperature thread locker?

High temperature is a little bit of a loose term so we had to give it some definition. 150°C (302°F) wasn’t high enough as all our Weiconlock range will handle at least that. Therefore, we chose 180°C as a cut-off point. All the grades listed below will handle at least this temperature while a few will withstand higher. A little arbitrary I’ll admit but we had to start somewhere.
