Product Description

Loctite 577 Fast Cure Medium Strength Pipe Seal 50ml is a curing gel suitable for fast applications at low temperatures such as outdoor plant maintenance. It carries DVGW, WRC, and NSF approvals.

This anaerobic thread sealant is recommended for all coarse metal threads up to 3 inches in diameter. It provides an instant low pressure seal that cures when confined between close-fitting metal surfaces to prevent leakage and loosening from shock and vibration.

Loctite 577 offers temperature resistance up to 150°C and has a medium disassembly strength. It is tested and approved according to EN 751-1 and BS 6956 type B standards for sealing gas fittings. The gel formulation allows for applications in cold weather conditions.

Key uses include sealing threaded connections in outdoor equipment, pipes, valves, and fittings in industrial plant maintenance and repair work. The fast cure time makes it ideal for temporary sealing of threaded joints during outdoor work.
