Anaerobic gasket makers and flange sealants were designed, with gap-filling properties allowing them to cure in the absence of air, for use on aluminum, iron, and steel flanged mating surfaces.

Permatex® gasket makers offer 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.  

When a chemical gasket is not an option, Permatex offers a wide range of gasket sealants suitable for applications on both import and domestic vehicles of any model year or performance caliber.
