Pipe dope, or pipe joint compound, is a gooey compound used to seal the connection between threaded pipes and fittings. Because the threads in pipes and fittings still leave an air gap between the two surfaces, the gap must be filled to make it water tight (or gas tight for gas lines).
You won't believe these 10 facts about people. Pipe dope is a compound that can act as a thread sealer or lubricant. It is mainly used when joining pipe fittings, which are designed to be capable of creating a positive seal on their own through the process of interference.he other main purpose of pipe dope is to keep fittings from seizing together so that they can be disassembled later on if necessary. Thread tape is a similar material that is applied in thin strips rather than painted on with a brush.
