Types of PVC pipe fittings or PVC fittings

1. PVC fittings based on shape or PVC fitting names

PVC Tee
PVC Tees fittings are used to connect three pieces of pipes in plumbing or drainage application. Tees have one inlet and two outlets that resemble the right angle (90 degrees) in the shape of T. It can be used to combine the flow from two inlets to one outlet as well in case of drainage. They are also used to spilt the flow into 2 outlets in plumbing.

PVC Wye or Y
PVC Wye fittings are used to connect three pieces of pipes. Wyes have one inlet and two outlets that resemble 120 degree angle in the shape of Y with two inlets coming together at 45 degrees into a single outlet in the drainage applications. It can be used to combine the flow from two inlets to one outlet as well.

PVC Elbow Joint or Bend
PVC Elbow connectors change the direction of flow between the two pipes connected. Common elbows found in the market have 90 degree & 45 degree bends. Elbow fittings are joined together to move around obstructions in the pipe run.

PVC Coupling
A coupler is a very short length of pipe or tube, with a socket at one or both the ends that let the pipes to be joined. Coupling is used to repair a broken or leakage pipe.

PVC Reducer
Plastic pipe reducer fittings are used to connect large diameter pipes to smaller diameter pipes. A reducer changes the pipe size to meet the hydraulic flow requirements of the system.

PVC End Cap
Cap fittings cover the end of the pipe to stop the flow of gas or water. They are used at the endpoint of the piping system and are also used in piping headers for future connections.

PVC Flange
Flange fittings are flat and round to create a tight seal with bolts and clamps. These types of pipe fittings are used when pipes are passed through walls, ceilings, and floors.

PVC Union
Just like couplings, union fittings also connect two similar pipes. There are three pieces in a union namely a nut, a female end, and a male end. As soon as the female and the male end are joined, the nuts provide the pressure needed to seal the joint.

PVC Valves
Valves are used to adjust the flow of fluids. There are two types of valves. Throttling, non-return, and isolation. Throttling valves control the pressure and amount of liquid flowing in the pipe. Non-return valves also are known as check valves that allow the liquid to flow in one direction.

PVC Adaptors (male & female)
Plastic adaptors are pipe fittings used to connect pipes that are of different types. Because an adaptor can be male or female on one end. In case the ends are non-threaded, they can be welded, soldered, or glued to the pipe. PVC adaptors are widely used in different types of water systems.

PVC bushing
Plastic bushings are called as reducer bushings and are used to connect two pipes of different sizes. The larger diameter of the bushing fits inside the larger pipe and the smaller end of the bushing fits inside the smaller pipe.
