Napoleon 10.3 Ounce Cartridge High-Temperature Sealant

Mill-pac, a high temperature sealant, comes in a 10.3oz caulking tube. This easy to use sealant is typically used on direct vent flex pipe to seal joints and wall penetrations where high temperatures are a factor. It's rated to 1050°F and remains flexible for a very long time to hold it's seal through the expansion and contraction of the metal components. The tube fits a standard caulking gun.

This 10.3 ounce container of sealant resists the high levels of heat that fireplaces, inserts, and stoves create, so it helps maintain the safety and integrity of your venting setup after installation and well into the future.
