100% genuine. 100% genuine Permatex, from authorized North American distribution.
A red, high-temperature RTV silicone gasket maker for parts such as exhaust manifolds, thermostat housings, valve covers, timing gear covers, water pumps and differential covers. It replaces most cut gaskets or can be used as a dressing, and is rated for continuous use from -54°C to 316°C (-65°F to 600°F) and intermittent use up to 343°C (650°F). Not for head gaskets or parts in contact with gasoline; its cure can corrode some surfaces, so Permatex points to its Ultra series for critical jobs.
Permatex Hi-Temp RTV Silicone Gasket is a single component, room temperature vulcanizing gasketing compound designed to provide reliable "formed-in-place" gaskets for mechanical assemblies. This material cures on exposure to moisture in the air to form a tough, flexible, silicone rubber gasket. The product resists aging, weathering and thermal cycling without hardening, shrinking or cracking. Designed to maintain maximum performance in a continuous temperature environment of 600F. OEM Specified.
