What Is Pipe Fittings?
Pipe fittings are the process where we divert the flow of the water by using piping components like tees, elbows, etc. In pipe fittings, we change the pipe sizes by using reducing tees, reducers, etc.
Here, we use coupling to connect the flow of water and caps to stop the water.
Types of Pipe Fittings
There are different types of joints are available, those are.
- Cross, Tee, Wye and Elbow Fittings
- Tee & Wye Fittings
- Cross Fittings
- Elbow Fittings
- Adapter, Bushing, Coupling and Union Fittings
- Coupling and Adapter Fitting
- Bushing Fittings
- Union Fittings
- Flange and Trap Fittings
- Trap Fittings
- Flange Fittings
- Plug, Cap, Nipple Fittings
- Cap Fittings
- Plug Fittings
- Nipple Fittings
1. Cross, Tee, Wye and Elbow Fittings
The list of cross, tee, wye and elbow fittings are as follows.
1.1. Tee & Wye Fittings
This is used to split the water flow into two parts or join the two water flows into one. The shape of Wye is like English letter ‘Y’ which is basically a 45-degree bend and it is used in drain application. A Wye has two inlets and one outlet. The side pipe of Wye is used to release the sewer gases in upward direction.
1.2 Cross Fittings
This type of fitting has four openings and here it is used as three inlets and one outlet or three outlets and one inlet. It is generally used in sprinkler systems or irrigation systems.
1.3 Elbow Fittings
This fittings have one opening and it has different bends of 90 degrees, 45 degrees, 60 degrees and 22.5 degrees. Elbow fitting is used to avoid obstructions in the pipe run.
2. Adapter, Bushing, Coupling and Union Fittings
The list of adapter, bushing, coupling and union fittings are as follows.
2.1 Coupling and Adapter Fitting
Coupling is used to connect two pipes, which slips over it and connects permanently. It is generally used to connect a large size pipe with a small one. Adapters are connected when different types of pipes are there like one is a normal pipe and other one is a threaded pipe.
2.2 Bushing Fittings
A bushing is used to reduce the pipe fitting because the inlet of this is large and outlet is small; that’s why it is called reducer bushing.
2.3 Union Fittings
Unions connect two same pipes by threaded rings or nuts. We can easily disconnect the connection by loosening the rings or nuts which is not possible in the coupling.
3. Flange and Trap Fittings
The list of flange and trap fittings are as follows.
3.1 Trap Fittings
Trap is basically a horizontal bend which is fitted in the drainage system of the kitchen or bathroom. The shape of traps are generally ‘U’ and ‘P’ shaped. The traps contain water which is used as the barrier which prevents entering the sewer gases.
3.2 Flange Fittings
4. Plug, Cap, Nipple Fittings
The list of plug, cap, nipple fittings are as follows.
4.1 Cap Fittings
This is generally used to stop the flow of the flowing materials. This is temporally used to stop when the plumbing work is ongoing.
4.2 Plug Fittings
Plus settings are used at the end of the pipe. A plug is only fits with a threaded pipe.
4.3 Nipple Fittings
It is a small section of male threaded which connects with two female thread.
