Loctite 510 – Flange sealant

Loctite 510 is a high-temperature, high-strength anaerobic flange sealant designed for sealing rigid machined metal flanges and close-fitting metal-to-metal joints. It cures in the absence of air when confined between metal surfaces, forming a durable, flexible gasket that effectively prevents leaks while resisting vibration, pressure, and thermal cycling.

Engineered for demanding industrial and automotive applications, Loctite 510 provides excellent resistance to high temperatures, oils, fuels, coolants, hydraulic fluids, and a wide range of industrial chemicals. It fills minor surface imperfections and machining marks, eliminating the need for conventional pre-cut gaskets and ensuring a reliable, leak-proof seal.

Once cured, Loctite 510 remains flexible, allowing it to accommodate slight movement and thermal expansion between mating flanges without cracking or shrinking. It is particularly well suited for rigid flanges made from aluminum, steel, and cast iron, where high-temperature sealing performance is essential.
