When temperatures soar, you need a gasket maker that won’t quit. This copper RTV is engineered for high‑performance and turbocharged applications, delivering reliable, super high‑temperature sealing up to 700°F (371°C). The neutral‑cure chemistry is non‑corrosive and oxygen‑sensor safe, so it plays nicely with modern engine materials and emissions systems.
Use it anywhere a tough, flexible, in‑place gasket is needed: exhaust manifolds, turbo flanges, downpipes, valve covers, intake manifolds, thermostat housings, oil pans, and water pumps. It cures to a resilient seal that won’t crack or shrink under thermal cycling, helping prevent leaks even where vibration and heat are relentless.
Crafted from premium RTV silicone, it resists oil, coolant, and most common automotive fluids (not recommended for direct gasoline contact). The low‑odor, neutral‑cure formula makes shop work more comfortable and safer for sensitive metals like aluminum.
Proudly made in the USA, this sealant supports American manufacturing and the craftsmanship mechanics count on. Whether you’re building, upgrading, or repairing, it’s a dependable, high‑heat solution you can trust under the hood.
