Permatex Hylomar Universal Blue is a professional-grade, non-chlorinated gasket dressing and flange sealant trusted by automotive manufacturers and racing teams worldwide. Formulated as a polyester urethane blue gel, it is specially engineered to remain non-setting and non-hardening even at elevated temperatures — making it an ideal sealing compound for demanding engine and drivetrain applications.

• Non-setting, non-hardening formula — stays flexible and tacky under heat, allowing repeated disassembly and reassembly without reapplication
• Wide temperature range — performs reliably from -60°F to +500°F
• No-run consistency — seals surface imperfections on machined flanges without migrating or dripping during assembly
• Vibration resistant — maintains a reliable seal in high-vibration environments
• Fluid resistant — withstands water, coolant, gasoline, lubricating oils, kerosene, and select refrigerants
