Thread Sealants“Leaks Don’t Stand a Chance!”<strong>Loctite</strong> ® thread sealants seal and secure metal pipes and fittings, filling the space betweenthreaded metal parts. Thread sealants harden to prevent leakage caused by vibration loosening,tape shredding, solvent evaporation, damaged threads, and temperature cycling. Designed forlow and high pressure applications, thread sealants seal instantly for on-line low pressuretesting. When fully cured, they seal to the burst strength of most piping systems.LOCTITE ® THREAD SEALANTPST ® STICK – High PerformanceThe <strong>Loctite</strong>® Thread Sealant PST® Stick isa single component, semi-solid anaerobicpipe sealant compound. The self -feedingapplicator stick facilitates application ofthe material where a conventional liquidor paste would be difficult to use. <strong>Loctite</strong>®Thread Sealant PST® Stick cures rapidly toprovide immediate low pressure sealing.The controlled lubricity prevents gallingand protects mated threaded areas fromrust and corrosion and eases disassembly.Recommended for sealing metaltapered pipe threads and fittingsin automotive applications.Typical Applications: Stainless steel fittings,oil and coolant lines, fuel fittings, rear axlefill plug, intake manifold switches, headbolts into through holes, oil psi sendingunits and sensors.Item Container Size Pack37615 19 g stick 6LOCTITE ® THREAD SEALANT 545 –Pneumatic/Hydraulic<strong>Loctite</strong>® Thread Sealant 545is designed for locking andsealing high-pressure pneumaticand hydraulic systems.
