Thread sealers, including liquid pipe dopes and PTFE tapes, are most often used in plumbing, automotive, and industrial piping systems wherever threaded pipe fittings, connectors, and valves are joined together. They are essential in residential water supply lines, natural gas piping, propane systems, heating and cooling HVAC networks, and hydraulic machinery. By lubricating the threads during assembly to prevent galling and filling the microscopic gaps between mating metal or plastic components, thread sealers ensure that high-pressure fluids, oils, compressed air, and volatile gases cannot escape through the spiral thread pathways, maintaining the safety and structural integrity of the entire system.
