Know the Benefits of Sealing Threads with a Pipe Thread Sealant
Using a pipe thread sealant is an important part of a plumbing job. It ensures that the gap between the fittings or pipe connections is sealed to prevent any leakage of gas or liquid. Pipe thread sealants are available in a variety of forms including liquid and compound, as well as tapes. Tapes are the most popular and are typically the safest, simplest, and most affordable option.
When choosing a sealant, it is important to consider the type of pipe being connected. For gas pipes and water pipes, Teflon tape is the recommended sealant. It is important to purchase a tape with a thickness of 3 to 4mm and a density of at least 1g/cc, as these will provide the best seal.
To use Teflon tape, start by wrapping the male pipe clockwise around the threads, pulling the tape tight so it will adhere to the threads. When completely covered, cut the tape, pressing the ends of the thread firmly. Then, connect the male pipe to the female pipe. Gently, tighten the connection with an adjustable wrench, being careful not to over tighten and break the pipes, and check for leaks.
Pipe dope, also known as anaerobic thread sealant, is thicker and better suited for pipes exposed to extreme temperatures. Before using it, both the male and female threads must be free of oil, dirt, and other debris. When applying the compound, make sure that a generous amount is put onto the male threads, connecting it to the female threads. Any compound leaking out of the connection should be removed immediately, allowing the sealant to dry. Then the connection should be tested for any leaks.
Using a pipe thread sealant is a simple, yet important, part of any plumbing job. By selecting the appropriate sealant for the type of pipe, and correctly wrapping and fastening it, you can ensure that the connection is properly sealed. This will prevent any leaks and ensure that the pipes are secure and functioning as they should.
