Henkel Loctite 55 Pipe Sealing Cord is a new, faster, more versatile pipe sealant which out-dates traditional tapes and hemp/pastes combinations. Impregnated with paste to give a high pressure seal to your joints. Loctite 55 should be wound a few times around the thread and once the joint has been closed tightly, will withstand pressures in the region of 40 bar. Use for cold and hot water applications, as well as potable water or gas. Use on copper, steal or plastic pipe systems.
