![]() For example, you will need to buy a specific pipe joint compound if it’s to be used for pneumatic connections, hydraulic, water, etc. And it also makes the pipe more resilient to higher pressures.ĭepending on their intended application, pipe dope can come in several types with different ingredients. It fills in all the small gaps and voids within the threads so nothing can work its way through them over time. Still, it also serves as a lubricant which makes the removal of the pipes easier in the future. ![]() It pulls double duty as an anaerobic chemical sealant, making any thread completely leakproof. Pipe Dope was used to address this problem. However, because of various variations in machine tolerances and the kind of materials that will pass through the pipe, which can expand/contract the material as it heats up/cools down, people started to find that pipes would eventually leak regardless of the machine quality. Most pipe threadings are pre-tapered during machining to provide a good ‘interference fit.’ Pipe Dope vs Teflon Tape: Are they the same?.What are the differences between Pipe Dope and Teflon Tape?.They are also commonly color-coded depending on what the pipe is supposed to carry. It’s a stretchy film that conforms to the shape of the threads. On the other hand, Teflon tape comes on a small spool and is wrapped around the thread just like how you could apply regular tape to something. This is usually used by professionals and for commercial applications. The main difference between pipe dope and Teflon tape is that pipe dope is a chemical pipe thread sealant that is brushed onto the thread in liquid form, which completely seals the thread. ![]() While both of these products aim to achieve the same thing – help seal the connection and prevent leaks, the way they do it and their intended use cases differ slightly. Plumbers use pipe dope and Teflon tape as two of the most popular kinds of thread sealer. So plumbers use an additional sealant to protect the threaded connection further and prevent any risk of leaks. ![]() Most plumbing pipes are joined together using a threaded connection as they are convenient, quick to install, and require no special tools.īut one of the problems they face is that no matter how good the machining of the threads is, they run the risk of leaking. ![]()
