- High-Temperature Service Sealant Formulation
Product Description
LOCTITE® 567™ is a one-component, low-strength anaerobic thread sealant designed for locking and sealing tapered metal pipes and fittings. The smooth, creamy off-white methacrylate ester paste cures when confined between close-fitting metal surfaces in the absence of air, helping prevent loosening and leakage caused by shock and vibration. Its high lubricity helps reduce galling during assembly, while robust cure performance, elevated-temperature capability, and oil tolerance support demanding industrial fluid-power and process applications.
Key features
- High-lubricity thread sealing: Helps prevent galling on stainless steel, aluminum, and other metal pipe threads and fittings.
- Robust anaerobic cure: Cures on active and passive metal surfaces and tolerates minor contamination from common industrial oils.
- High-temperature service: Supports demanding metal-thread applications with resistance to elevated temperatures and a range of industrial fluids.
