Choosing a thread sealant
Start with the material and the fluid or gas in the line, then the working temperature and pressure. Strength is how hard the joint is to break apart again, so use a low strength grade where you expect to service the fitting often. The 5770 is the one listed for high temperature. The titles do not give fluid compatibility, pressure ratings, temperature limits or approvals, so check the data sheet for each product. Always check the data sheet. It is the source for those details.
