Permatex, an innovator in chemical technology for automotive maintenance and repair, has introduced a new advanced formula RTV Gasket Maker that is specially designed for use on vehicles with synthetic motor oils. The new Permatex Ultra Synthetic RTV Gasket Maker is formulated to resist the aggressive chemical properties used in today’s synthetic oils and prevent leak paths commonly associated with synthetic oil applications.

Permatex Ultra Synthetic RTV Gasket Maker can be used as either a formed-in-place gasket maker or sealant and is highly recommended for close tolerances and high-performance parts. Applications include oil pans, valve covers, oil pumps, timing gear covers, intake manifold end seals and more.

Permatex Ultra Synthetic RTV Gasket Maker provides excellent adhesion and flexibility, and maintains a tough, reliable silicone rubber seal. According to the company, it will not harden, shrink or crack. The gasket maker also is low odor, non-corrosive, non-flammable and sensor safe. When cured, it creates a flexible seal that resists aging, weathering and thermal cycling, and has a temperature resistance is up to 500 degrees F.
