Description
When you’re dealing with engine gaskets that need to seal tight under serious heat, regular silicone just doesn’t cut it. This copper-enhanced RTV silicone is specifically formulated to handle the high temperatures you’ll find around exhaust manifolds, oil pans, and other hot engine components on your tractor or equipment.
What You’re Getting
- High-temperature copper formula that stays flexible even when things get hot
- Creates a permanent, flexible seal that moves with thermal expansion and contraction
- Sensor-safe formula won’t damage oxygen sensors or other electronic components
- Ready-to-use squeeze tube design makes application quick and clean
- Oil and coolant resistant – won’t break down from exposure to fluids
Built for Real Farm Work
This gasket maker is ideal for sealing oil pans, valve covers, transmission pans, and differential covers on tractors, combines, and other heavy equipment. The copper content makes it especially good for applications where you need heat resistance and a permanent seal that won’t leak when your machine’s working hard.
Made to Last
The copper particles in this formula give it superior heat resistance compared to standard RTV silicones. It forms a tough, permanent gasket that handles the vibration and temperature cycling that comes with agricultural equipment use. Once cured, it creates a reliable seal that’ll keep doing its job season after season.
Good to Know
Clean both surfaces thoroughly before application and allow 24 hours for full cure before adding fluids. This stuff sets up within an hour, so work at a steady pace once you start applying it. Keep the tube cap tight between uses to prevent skinning over in the tube.
