Loctite brand thread sealants seal and secure plastic and metal pipes and fittings. By filling the space between threaded metal parts, thread sealants harden to prevent leaking. Designed for low and high pressure applications, thread sealants seal instantly for low pressure testing. When fully cured, they seal to the burst strength of most piping systems. For repairs, parts may be disassembled with basic hand tools. Application: For stainless steel, aluminum, galvanized metal and other inert metals
