The new Permatex Ultra Synthetic RTV Gasket Maker is formulated to resist the aggressive chemical properties used in today’s synthetic oils. Highly recommended for close tolerances and high performance parts, the gasket maker can be used as either a formed-in-place gasket maker or sealant. The gasket maker is also low odor, non-corrosive, non-flammable, and sensor safe. When cured, it creates a flexible seal that resists aging, weathering, and thermal cycling. Temperature resistance is up to 500° F. (877-376-2839/www.permatex.com)
