Loctite 567 Thread Sealant 50ml

LOCTITE® 567 is a high-performance single-component anaerobic thread sealant specifically developed for sealing and locking tapered metal threaded fittings and pipe connections. It cures in the absence of air between close-fitting metal surfaces, creating a durable seal that prevents leakage caused by vibration, shock and pressure fluctuations.

Its white, high-viscosity formulation is designed for coarse-threaded metal pipes and fittings. The product's excellent lubricating properties ease assembly and help prevent galling on stainless steel, aluminium and other metal threads. It also provides outstanding chemical and thermal resistance, ensuring long-term sealing performance in demanding industrial environments.
