Loctite® 577 Thread Sealant (50 ml)

Loctite® 577 is a high-performance thread sealant designed for sealing metal threaded pipes and fittings, preventing leaks caused by vibration, pressure, or temperature changes.

Commonly used in marine plumbing, hydraulic systems, and gas installations, it provides reliable sealing while also locking the threads to resist loosening. The sealant cures anaerobically in the absence of air when confined between metal surfaces.

Supplied in a 50 ml bottle, Loctite 577 allows for accurate application and is suitable for both maintenance and installation work on board.
