1- Knee
Elbows are among the most common and practical connections that are used in piping systems and to change the direction of pipes. Since it is not possible to bend many pipes, elbows must be used to change their angle and direction. Elbows can have different types, such as 45°, 90°, etc., and increase the speed of piping.

2- Bushes
3- Conversions
Conversions are also other connections that can connect pipes or other equipment to each other. In fact, conversions can connect different pipes and fittings of different sizes. Conversions can have different types of size and material, like electric pipes, and they will be concentric and non-concentric.
4- Box of Division
Another one of the most practical fittings used in electrical piping systems is the distribution box, which can be circular or square in shape. The most important use of the distribution box is to connect the pipes to each other at a specific point and create a branch from the wires inside the box.

5- Cover
Another connection that can be used a lot in piping systems is the cap. These fittings are used to block pipes and junction box holes.
6- Door Fittings
The use of closed joints is done when the work path is long and two bends are used along the pipe path. These connections are also used when other connections are used, such as intersections, pipe branching, tees, closed elbows, etc. This type of connection has a small volume, and for this reason, the branching of the wires will not be allowed, and their most common use is better guidance of springs and ease of wiring.
7- Metal Package
Another connection that is used in electrical piping systems is the clamp, whose main function is to hold or connect the pipes to the desired location. Fasteners are usually made of metal and to prevent corrosion and rust, a protective layer is covered on them and they are used based on the size of the electric pipe.
