Product description

Size:3 Ounce Tube

Permatex Ultra Copper Maximum Temperature RTV Silicone Gasket Maker is the most advanced, high temp RTV silicone gasket available. Three times more oil resistant than conventional silicones and eight times more flexible than cut gaskets, it is sensor-safe, low odor, and non-corrosive with superior adhesion. Highest operating temperatures for 4-cylinder, turbocharged or high-performance engines and OEM specified, with a temperature range of -75 degrees fahrenheit to 700 degrees fahrenheit intermittent. Also resists auto and shop fluids and vibration. These gasket makers offer significant performance advantages, excellent torque retention and hi-temp, sensor-safe properties. Extended warranties, engine sensors and new component materials such as aluminum, bi-metal alloys and high-tech plastics, have created the need for superior RTV silicone gasket makers in both OEM production and service applications. Permatex always has the right gasket maker for your application.
