Over a Century of Automotive Chemistry
Permatex traces its origins to 1909 and founder Constant Benoit's laboratory in Brooklyn, New York, making it one of the oldest automotive chemical companies in America. The brand built its initial reputation on gasket-making compounds — products that seal engine surfaces and prevent fluid leaks in the high-temperature, high-pressure environment of automotive engines. For over a century, Permatex has been the default choice in professional repair shops for sealing solutions that have to work reliably.
The product line has expanded considerably from those early gasket compounds into a comprehensive system of automotive chemicals: thread lockers that prevent fastener loosening, RTV silicone sealants for custom gasket fabrication, penetrating oils, anti-seize compounds, and adhesives. Production at the Solon, Ohio manufacturing and technical center maintains the chemical engineering heritage that established Permatex as the industry standard.
From Gasket Maker to Complete Chemical System
Permatex's Form-A-Gasket sealants remain the core of the product line — both the original anaerobic formula and the RTV silicone version are standard equipment in professional shops. The Right Stuff Gasket Maker provides an instant-cure alternative for applications where overnight drying time isn't practical. Thread Locker in blue (medium strength) and red (permanent) covers fastener applications from assembly to service.
For automotive DIY work, Permatex products provide professional-grade chemistry available at auto parts stores across the country. The Connecticut production and century-plus track record make Permatex the reliable choice for repairs that need to hold up to the demanding conditions inside an engine or drivetrain.
