Are Hilti fire stop products compatible with one another, and can different products be used in the same opening?

Hilti firestop products are chemically compatible with one another.
Many firestop systems, such as C-AJ-2109 call for more than one Hilti firestop product. If you have a condition involving multiple firestop products used together, it is best to reach out to our firestop engineering group at usfirestopeng@hilti.com for assistance.
It may result in the need for an engineering judgment.
