Anaerobic Gasket Maker EACH - Permatex

The Permatex 51817-CAN Anaerobic Gasket Maker is a professional-grade, medium-strength, thixotropic sealant designed to create reliable, leak-proof, form-in-place gaskets on rigid flanged connections. This advanced red gel cures quickly when confined between close-fitting metal surfaces, eliminating the need for conventional pre-cut gaskets in demanding automotive and industrial environments.

Key Features

• Durable, Leak-Proof Seals: Forms tough, resilient, and solvent-resistant seals that cure rapidly, ensuring long-term integrity and effectively preventing leaks in high-demand applications.
• Accommodates Dynamic Movement: Engineered to flex with flange movement, maintaining seal integrity under vibration, pressurization, and thermal cycling without compromising performance.
• Non-Corrosive & Certified: Safe for use on aluminum, iron, and steel components, preventing pitting or discoloration. This product meets OEM specifications and is NSF White Book registered.
• Simplified Application & Disassembly: A single-component product requiring no mixing, it cures only when confined, preventing premature hardening. Components remain easy to disassemble for future service, and old gasket material can be removed efficiently.
• Fills Surface Imperfections: Effectively seals gaps up to 0.015 inches (0.38 mm), creating a secure bond even on machined surfaces with minor irregularities.

Applications

This versatile anaerobic gasket compound is ideal for creating reliable form-in-place gaskets on rigid flanged connections in both automotive and industrial settings. It is commonly utilized for sealing machined aluminum metal components, including gearbox and engine castings, pumps, thermostat housings, transmission pans, transmission case covers, transaxle casings, transfer cases, axle covers, gear cases, and split crankcases. It also serves as an effective O-ring replacement in many applications where a robust, anaerobic seal is required.
