Permatex Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker 88g
Permatex Ultra Grey Rigid High-Torque RTV Silicone Gasket Maker 88g is a professional-grade OEM-specified RTV silicone gasket maker engineered for modern automotive and heavy-duty equipment that require rigid, high-torque sealing performance. Developed to meet today’s advanced engine and drivetrain requirements, it creates durable formed-in-place gaskets that resist oil, vibration, and thermal cycling while maintaining a reliable leak-proof seal.
Its sensor-safe, low-odor, and non-corrosive formula protects sensitive engine components and electronic sensors while providing excellent adhesion to metal surfaces. Unlike conventional gasket materials, Permatex Ultra Grey remains highly flexible after curing, making it eight times more flexible than cork or composite gaskets and three times more oil resistant than standard RTV silicones.
The advanced silicone formulation withstands intermittent temperatures from -54°C to +260°C (-65°F to +500°F) while resisting engine oil, transmission fluid, coolant, shop fluids, and vibration. It performs exceptionally well in high-torque applications where rigid flange sealing is critical for long-term reliability.
Automotive technicians and industrial maintenance professionals trust Permatex Ultra Grey for sealing valve covers, oil pans, automatic transmission pans, timing covers, thermostat housings, water pumps, intake manifold end seals, differential housings, axle shaft flanges, rear axle assemblies, and power divider housings.
Whether used during new assembly or maintenance repairs, this premium RTV silicone gasket maker provides long-lasting protection against leaks while eliminating the need for traditional paper, cork, or composite gaskets.
