Can you ‘mix and match’ components from different manufacturers? Penetration sealing

The simple answer is no.

It is very unlikely that the different components have been tested together. Without fire test evidence to show that the mixture of components will provide the required fire resistance, you have no guarantee of the seal’s intended performance.

A secondary question would be: Has there been any testing for compatibility? Although products can look very similar, they may be chemically different and, again, without supporting test evidence, there is no assurance that the mixture of products will perform as intended. There would be no certainty of the issues that it may cause after a long period of time or in fire conditions. Therefore, it is not worth the risk of potentially compromising the fire stop seal.
