Product Description
Permatex Ultra Copper Maximum Temperature RTV Silicone Gasket Maker is a premium, single-component, room-temperature vulcanizing (RTV) gasketing paste designed for high-performance mechanical assemblies. Tested and verified to exceed OEM specifications, this advanced copper-colored formula relies on ambient moisture to cure into a tough, permanently flexible silicone rubber seal.
It offers the ultimate protection against structural thermal cycling, extreme heat up to
700F (371C), and continuous vibration. It is specifically engineered to resist common workshop and automotive fluids while providing up to
3 times greater oil resistance than conventional silicones and
8 times higher flexibility than pre-cut stamped gaskets. The sensor-safe, low-odor, and non-corrosive composition ensures zero interference with electrical and automated engine control units.
Designed for Maximum Heat ResistancePermatex Ultra Copper Gasket Maker offers unmatched temperature resistance, making it the go-to solution for sealing and repairing exhaust systems and other high-heat components. Its advanced silicone formula resists thermal cycling and maintains superior flexibility, preventing cracks and leaks over time.
Precision Application with OEM ReliabilityEach 85g tube includes a nozzle applicator for controlled, mess-free application on metal surfaces. Meeting stringent OEM specifications, the RTV silicone ensures proper sensor compatibility, enabling reliable, long-lasting repairs in both automotive and industrial maintenance environments.
Versatile Uses Across IndustriesBeyond typical automotive repairs, this copper-tinted RTV silicone is widely used in industrial maintenance for high-temperature sealing. Its superior adhesion and durability allow it to thrive in harsh conditions, ensuring lasting performance for distributors, exporters, importers, and manufacturers.
FAQ's of Permatex Ultra Copper Maximum Temperature RTV Silicone Gasket Maker 81878 85gm:
Q: How do I properly apply Permatex Ultra Copper Maximum Temperature RTV Silicone Gasket Maker?
A: Clean and dry the metal surface before applying a continuous bead with the tube nozzle. Position and assemble parts within 5 minutes. Allow the silicone to cure in place for up to 24 hours, depending on the thickness of the bead, before subjecting the assembly to high temperatures.
Q: What are the ideal usage scenarios for this gasket maker?
A: This product is specifically designed for applications requiring resistance to extreme heat, such as exhaust manifold repairs, header sealing, turbocharger gaskets, and general high-temperature sealing tasks in automotive and industrial settings.
Q: When does the RTV silicone fully cure and become ready for heat exposure?
A: Full cure occurs within 24 hours, depending on bead thickness and ambient temperature. Only expose the assembly to high-heat conditions after the product has fully cured for optimal performance.
Q: Where can I use Permatex Ultra Copper Gasket Maker safely?
A: It is safe for use on most metal surfaces commonly found in exhaust systems, including manifolds, headers, and turbocharging components. It is also sensor-safe, making it compatible with modern engines' oxygen and other sensitive sensors.
Q: What benefits does this RTV silicone offer compared to standard gasket makers?
A: Permatex Ultra Copper provides superior high-temperature resistance, avoids cracking or shrinking, and maintains excellent flexibility under stress. Its OEM approval ensures dependability in critical repairs where sensor-safety and performance are essential.
Q: How long is the shelf life of the unopened product?
A: When stored unopened, the product remains effective for up to 18 months from the date of manufacture, ensuring reliability whenever you need it.
