Description

Permatex High-Temp Red RTV Silicone Gasket Maker is formulated for high temperature applications or heavy-duty use such as towing. It 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. Resists auto and shop fluids, with a temperature range of -65 degrees fahrenheit to 650 degrees fahrenheit intermittent. A first generation 1970-1980 gasket maker, it is OEM specified. Permatex offers significant performance advantages which include outstanding oil resistance, 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.

  • Does what I need.
Size: Pack of 1 Style: 3 oz.
My pre-cats' (which are tucked inside the engine bay/compartment area, instead of the underbody) heat shields were rusty and loose after I did some exhaust work, and I needed to find a way to bind them together so they don't rattle every time I accelerate.

It didn't happen but it was very difficult to squeeze out along the valve cover. I have been using the mower for about two months and no leaks. This product works great. ... show more
