6 Types of Plumbing Fittings

Pipe fittings are an essential component of every piping and plumbing system, making them particularly important in industrial and commercial settings. Pipes can be linked together or installed in the correct location with the help of fittings. There are different types and sizes of plumbing fittings, and each one has a unique installation process.


Today, we will shine some light on different types of plumbing fittings, and at the end of this article, you will know how to distinguish them. Let us get started.


1. Elbows


Elbows are plumbing fittings that will help you change the flow’s direction. We have two types of elbows, 90 and 45-degree elbows. 90-degree elbow helps to change the direction of flow by 90 degrees. On the other hand, a 45-degree elbow helps to change the flow direction by 45 degrees.


2. Reducer

A reducer is a component of a pipe fitting that decreases the size of the flow from its bigger to its smaller state by decreasing the size of the pipe. In most cases, you can choose between two distinct kinds of reducers. The first type of reducer is called a concentric reducer, and it looks like a cone and gradually tapers off as it goes around the pipe.


However, air can accumulate in this configuration, which leads to cavitation. The other type is called an eccentric reducer, and it differs from the standard reducer in that it has one edge parallel to the connecting pipe. It prevents air accumulation from occurring.


3. Coupling

When connecting pipes of the same diameter, a coupling is required to make the connection. If the pipe breaks or a leak develops, couplings might also be of assistance. In most cases, two distinct kinds of couplings can be used: compression and slip.


A compression coupling is a standard coupling that is connected between two pipes. It prevents leakage by arranging gaskets or rubber seals on both sides of the connection, or glue is provided if neither of those options is possible.

The inner pipe of a slip coupling can slide up to some length, making the installation of the coupling much simpler. It also has two pipes that are positioned as one into the other. Therefore, you can repair pipes of great lengths damaged by using slip coupling.


4. Union

A union is a specific kind of fitting that serves a purpose analogous to that of a coupling. However, you cannot undo it after you fix it; on the other hand, we can undo the union whenever necessary. The components of a union are a nut and male and female ending threads. Thus, a union can also help to maintain a pipe.


5. Adaptors

Adaptors transform the ends of pipes that do not have specific threading into male or female threading, depending on the system’s requirements. Copper and polyvinyl chloride (PVC) pipes typically require adapters. Male threads are available in male adapters, while female threads are available in female adaptors.


6. Valves

Valves are plumbing fittings that you can utilize to either stop the flow of fluid in its route or to regulate fluid flow. There are many varieties of valves available, each one optimized for a particular set of circumstances. The following is a list of some key types of valves.


  • Gate valve
  • Plug valve
  • Ball valve
  • Globe valve
  • Check valve
  • Butterfly valve
