The Story
Loctite 518 Gasket Maker is a high-performance, anaerobic flange sealant designed for use on rigid iron, aluminum, and steel flanged mating surfaces. This versatile sealant cures in the absence of air to form a flexible, durable seal that resists leakage and withstands minor surface imperfections. With easy application and reliable results, Loctite 518 is ideal for use in automotive, machinery, and industrial maintenance where high chemical and temperature resistance are essential.
Key Features:
-
Forms Reliable Seals: Fills gaps up to 0.25mm for effective sealing.
-
Wide Compatibility: Suitable for use with metal flanges (aluminum, cast iron, steel).
-
Easy to Apply: Single-component, no mixing required—just apply and assemble.
-
High Resistance: Withstands oils, coolants, and solvents; operating temperatures from -55°C to +150°C.
-
Reduces Inventory: Replaces conventional paper, cork, and rubber gaskets for a cleaner, more reliable seal.
Applications:
Perfect for gearboxes, pumps, and engine flanges. Ideal for automotive, heavy equipment, agricultural, and industrial repairs.
