MC4® | Heating System Leak Sealer
Our highly concentrated MC4 is an incredibly effective way to deal with small leaks. Protecting and sealing from the inside, it can infiltrate really hard-to-reach places, reducing the need for a more costly repair. One dose could be all it takes to fix the leak and restore pressure.
MC4+® available in Rapide
MC4+ Rapide isn’t just powerful – it’s fast too. The high concentration guarantees a strong seal. Because it flows around the entire system, it gets to work even in tough-to-reach places. And with its quick-dose bottle design, 20 seconds is all it takes to add it to the system.
