Description
The Permatex Ultra Copper RTV Silicone Gasket Maker is a premium high-temperature silicone designed to withstand extreme heat conditions up to 700°F (371°C) intermittently. This OEM-specified, sensor-safe, non-corrosive formula forms a flexible, durable “formed-in-place” gasket, ensuring superior sealing performance in high-performance engines.
Key Features & Benefits
- High-Temperature Resistance: Withstands continuous exposure up to 600°F (316°C) and intermittent spikes up to 700°F (371°C).
- Sensor-Safe & Non-Corrosive: Ideal for modern engine components and electronics.
- Superior Adhesion & Flexibility: Bonds securely while remaining pliable to resist cracking, shrinking, and hardening.
- Oil & Chemical Resistant: Maintains integrity when exposed to motor oils, transmission fluids, alcohol, and antifreeze.
- Replaces Traditional Cut Gaskets: Forms a reliable seal without pre-cut gaskets, reducing material costs and installation time.
- Low Odor & Non-Flammable: Safe for automotive and industrial applications.
