The Loctite PST Stick is a single component, semi-solid anaerobic pipe sealant compound. ò The self-feeding applicator stick facilitates application of the material where a conventional liquid or paste would be difficult to use. ò Loctite PST stick cures rapidly to provide immediate low-pressure sealing. ò The controlled lubricity prevents galling and protects mated threaded areas from rust and corrosion and eases disassembly. ò Recommended for sealing metal tapered pipe threads and fittings.
