Permatex® High-Temp Red RTV Silicone Gasket Maker


OEM specified. Formulated for hi-temp applications, or heavy-duty use (such as towing, etc.). Replaces almost any cut gasket by making reliable “formed-in-place” gaskets that resist cracking, shrinking and migrating caused by thermal cycling. Coats pre-cut gaskets to increase reliability. Temperature range -65ºF to 650ºF (-54°C to 343°C) intermittent; resists auto and shop fluids.


Suggested Applications: Valve covers, oil pans, timing covers, and thermostat housings.

  4. Silicone will skin over in one hour and fully cure in 24 hours under normal conditions. Allow more time for cold or very dry conditions.
  5. Clean uncured silicone from hands, tools and clothing with Fast Orange® Hand Cleaner.
