Permatex Ultra Copper Gasket Maker - Ideal for high-temperature applications

Permatex Ultra Copper Gasket Maker is ideal for high operating temperatures common in 4-cylinder, turbocharged or high-performance engines. The most advanced, high temp RTV silicone gasket maker available. This gasket maker is sensor-safe, low-odour, noncorrosive making it ideal for installing oil pressure sensors, thermo fan switches etc. This gasket maker features superior adhesion which means it offers great resistance to nasty surprises or leaks. It is also three times more oil resistant than conventional silicones which means it won't degrade when coming into contact with engine oil or other fluids. It is eight times more flexible than regular pre-cut gaskets, further increasing its strength and reliability. The temperature range is -54°C to 371°C, so we think it'll hold up just fine to any extreme weather conditions or hash under-bonnet temperatures.
