LOCTITE® 577, Medium-Strength, General Purpose Thread Sealant

Medium-strength, general purpose thread sealant for straight/straight and straight/taper threads and fittings. Fills the space between threaded parts and seals and locks at the same time.
When you need a general purpose thread sealant with high temperature- and contamination-tolerance, as well as effectiveness on inactive and active metals, choose LOCTITE® 577. Designed for the locking and sealing of threaded metal pipes and fittings, this product provides an instant, low-pressure seal and won't creep, shrink or shred. Perfect for use on stainless steel without the need for surface activation, it offers gap performance to 0.01in (0.25 mm) and will cure even in the presence of minor surface contaminations from cutting, lubrication, anti-corrosion and protection fluids, or cleaners containing surfactants and corrosion inhibitors. Meets the performance requirements of KIWA GASTEC QA AR 214 for admixtures up to and including 100 % hydrogen gas – certifications are available in select countries.
