High-Temperature Copper Silicone Sealant – Superior Resistance & Perfect Fit (85g)
- Specially formulated for high-performance engines and extreme temperatures, this premium copper silicone sealant outlasts and outperforms traditional sealants with exceptional flexibility and durability.
- Withstands temperatures up to 371°C, making it ideal for exhaust systems, valve covers, thermostat housings, water pumps, oil pans, and other high-heat components.
- Resistant to oil, coolant, water, and other engine fluids, ensuring a long-lasting seal even under intense use. The copper content delivers excellent heat conductivity to prevent thermal damage at joints.
- Non-corrosive and safe for use on aluminum, stainless steel, and cast iron surfaces. Recommended for engines with oxygen sensors, as it won’t release substances that might affect sensor performance.
- Easy to use: The tube design allows for precise application. The sealant cures quickly to form a flexible, vibration-resistant layer—an outstanding alternative to cork, rubber, and regular silicone gaskets. It won’t shrink or harden, guaranteeing reliable sealing.
- Low-odor formula makes it suitable for indoor use in garages or workshops. Trusted by automotive professionals, maintenance specialists, and industrial users alike.
