Professional sealing with Henkel Loctite 577

Henkel Loctite 577 is a high-performance liquid thread sealant designed for metal threaded connections. It provides reliable sealing of pipes and fittings exposed to pressure or high temperatures. Thanks to its liquid consistency, Loctite 577 fills all gaps in the thread, creating a long-lasting seal that prevents leakage and loosening caused by vibration.

Technical features

Loctite 577 adheres perfectly to metals such as steel, brass and stainless steel. It cures anaerobically – in the absence of air and in contact with metal – forming a strong and durable seal. The compound is resistant to water, oil, gas, glycol and many chemical fluids. It also maintains its sealing properties over a wide temperature range, ensuring reliable performance in demanding conditions.

Applications

Loctite 577 is widely used in heating and cooling systems, sanitary installations and industrial applications. Installers often apply it in boilers, compressors and pipe networks where absolute reliability is essential. The liquid can be applied directly to the thread, making assembly quick and efficient.
