A plumbing coupling is a type of pipe fitting that joins two or more pipes together to form one larger pipe. It provides continuity between pipes of equal or different sizes. Depending on the coupling design, it may connect one pipe to two others. Flexible couplings are useful for piping repairs, especially in the water and wastewater industry. Listed below are some common types of pipe couplings. Learn how to use one of these tools.
An elbow coupling is an example. It features a bend like an arm joint and is used to change the direction of flow of water in a pipe. There are several degrees of elbows, including 22.5 degrees, 45 degrees, and 90 degrees. Reducer elbows are similar but are used for smaller or larger piping diameters. These fittings can be made of different materials. While most elbows are female, there are also mechanical elbow fittings. These couplings attach to two pipes by screwing or gluing.
Union fittings are another type of plumbing coupling. These fittings allow for easier installation of pipes with different materials and make the process of reassembling easier. They are used to join two pipes and are best suited for areas where plumbing tape or thread compound cannot be applied. Regardless of the type of plumbing coupling, it is crucial to know how to use one properly. There are many different types of plumbing couplings, but they all serve the same purpose.
Tees are a common type of pipe coupling. They come in many different sizes and are used for connecting two pipes. A tee will connect two pipes with similar sizes and will also make the flow direction as one. A tee is available in different materials, including ABS, copper, CPVC, PVC, brass, malleable metals, and stainless steel. A tee is a versatile fitting that is extremely useful for many applications.
