The Permatex High-Temp Red RTV Silicone Gasket Maker is specially formulated for demanding, high-temperature sealing tasks in automotive, industrial, and heavy-duty applications. It effectively replaces traditional cut gaskets by forming a durable, flexible, and heat-resistant seal directly on parts and surfaces.

This professional-grade RTV silicone is designed to withstand extreme thermal cycling, preventing cracking, shrinking, and shifting under pressure and heat. It’s ideal for use on valve covers, exhaust manifolds, timing covers, thermostat housings, and more.

Key Features:

  • Withstands temperatures up to 650°F (343°C) intermittent

  • Ideal for high-heat and heavy-duty gasket applications

  • Creates strong, formed-in-place gaskets for leak-proof seals

  • Resistant to oil, transmission fluid, antifreeze, and most shop chemicals

  • Non-corrosive, sensor-safe formula

  • Packaged in a convenient 11 oz cartridge

Applications:
Perfect for use in automotive engines, industrial equipment, trucks, marine engines, and more—anywhere reliable, high-temperature sealing is required.
