LOCTITE 577 - Thread Sealant for Hydrogen Application

LOCTITE® 577 is a yellow, high viscosity anaerobically curing thread sealant that is specially formulated to reliably secure and seal metal pipes, fittings and other threaded connections.

The product provides an immediate low pressure seal and does not creep, shrink or fray upon assembly.

Ideal for use on BSPT and NPT metal threads.

LOCTITE 577 has excellent chemical resistance.

The product has been deemed hydrogen ready for use on metal fittings only, according to GASTEC QA AR 214. Class 8.

Key features

Excellent chemical resistance and easy to apply.

Medium-strength, vibration resistant thread sealant for metallic threads.

Immediate sealing effect against low pressures.

NSF P1 Reg. No. 123001.

DVGW approval (EN 751-1): DVGW Reg. No. NG-5146CQ0312.

Particularly suitable for use on stainless steel without the need for surface activation.

It not only works on active metals (e.g. brass, copper) but also on passive substrates such as stainless steel and plated surfaces.

It cures in the presence of minor surface contaminations from various oils, such as cutting, lubrication, anti-corrosion and protection fluids and cleaners containing surfactants and corrosion inhibitors.
