PVC Pipe Fittings Names: Different Types and Which to Use?

Many people may have heard of PVC pipe fittings, but perhaps not all of the names of it. To put simply, PVC pipe fittings, which are a necessary part of contemporary plumbing, provide a useful substitute for more conventional materials like copper water pipes. Plumbing systems in both homes and businesses frequently use PVC pipe fittings because of its dependability, adaptability, and affordability. As the title suggests, this article will offer a succinct overview of the several kinds and uses of PVC pipe fittings, emphasising their designations and importance in the plumbing sector.

Comprehensive List of Common PVC Pipe Fittings’ Names

Fitting TypeDescription
Elbows Used to change pipe direction
TeesT-shaped, split flow into two
CouplingsConnect two pieces of pipe
UnionsAllow quick disconnection/reconnection
ReducersConnect pipes of different diameters
Caps and PlugsClose off the end of a pipe (Caps) or an opening in a fitting (Plugs)
BushingsJoin pipes of different sizes
CrossesX-shaped, connect four pipes
WyesY-shaped, create a 45-degree branch
AdaptersTransition from PVC to other materials

Some of the most commonly known PVC pipe fittings in plumbing are included in this short list, each of which has a distinct purpose inside the system. Effective plumbing solutions require an understanding of the names of these fittings and the uses for which they are intended. For more info, you can check out UNITRADE’s catalogue of PVC pipe fittings as the names are also listed there as well.

Types of PVC Fittings

This section right here provides a more in-depth detailed description of the PVC pipe fittings. Here, the names of the PVC pipe fittings are listed down and you can also understand more on how to apply the pipe fittings into practice.

1. Elbows


These connectors are essential for reversing the flow of water in a pipeline. They can be found at many angles, most often 45° and 90°, which makes it possible to route pipes in both residential and commercial structures in a variety of ways, including around corners and obstructions. 

2. Tees


In a plumbing system, tees are used to generate branch lines. They are necessary in situations like house plumbing systems for sinks, showers and outdoor taps, when a single water supply line must distribute water to several outlets.

3. Couplings 

Fittings such as couplings are made to join two pipes of the same diameter, they are essential for expanding already-existing pipelines and fixing damaged sections. They are a standard in practically all PVC plumbing work because to their ease of use and efficiency.

4. Unions

Similar to couplings, unions are made especially for situations where pipes may need to be taken apart and put back together on a regular basis, like in filter systems or other plumbing setups that need to be maintained.

5. Reducers 


When connecting pipes of varying diameters, reducers are utilised to provide a seamless transition that keeps the system’s water pressure and flow rate within acceptable limits. They are especially helpful in large-scale plumbing systems where different pipe diameters are frequently encountered.

6. Caps and Plugs 


Caps are used to seal pipe ends to stop water flow and safeguard pipe ends, whereas plugs have a similar function too to seal off an aperture in a fitting. When some parts of a plumbing system are not in use, both are necessary to keep the system together.

7. Bushings 

The purpose of bushings is to accommodate varying pipe diameters in a plumbing system. They are particularly helpful in intricate installations where different pipe diameters are needed to provide precise pressure and flow requirements.

8. Crosses

Cross fittings are used to connect four pipes at a single junction point. They are less frequent in basic domestic plumbing systems but essential in more intricate systems such as large-scale industrial plumbing or irrigation networks.

9. Wyes

Wye fittings are used to branch off a main line at a 45-degree angle. Their design is perfect for waste and vent lines in plumbing systems, as they help to eliminate clogs by promoting a smoother flow of waste material.

10. Adapters

Adapters are important for switching PVC pipe to other kinds of piping materials, such copper or steel. This is especially helpful in systems where PVC piping must be connected to fixtures or existing metal pipes.

In a plumbing system, every kind of PVC fitting has a distinct purpose that guarantees the effective and leak-free delivery of water. Their wide range of uses demonstrate how adaptable PVC is as a material to suit various plumbing circumstances and needs.

Advantages of Using PVC Fittings in Plumbing

Durability and Longevity

PVC fittings provide a respectable level of durability. They do not easily rust, corrode, or degrade, which is a common problem with steel or copper fittings. Because of their durability, they can be used in a variety of plumbing settings, including indoor plumbing and subterranean water systems.

Corrosion Resistance

PVC’s resistance to corrosion is one of its best qualities. The fittings along with the pipes does not corrode when exposed to water and various harmful chemicals such as concentrated acids and so on compared to metallic fittings. This feature keeps the water supply clean and guarantees the longevity of plumbing systems.

Ease of Installation

Because PVC fittings are lightweight and simple to use, installation requires less effort. They are simple to cut and assemble, which cuts down on installation time and labour expenses. This is especially helpful for large-scale projects where a significant amount of labour and supplies may be required.


PVC fittings are typically less expensive than materials like copper. Their affordability, along with their longevity and simplicity of installation, leads to immediate and long-term cost savings. PVC is therefore a cost-effective option for a variety of plumbing projects.

Chemical Resistance

As PVC is resistant to a wide variety of chemicals, it can be used in both industrial and domestic environments where different kinds of wastewater are present. The piping system’s longevity is further enhanced by this chemical resistance, which guards against harm from a variety of chemicals such as alcohols, oils, and so forth.

Installation Tips and Best Practices

Accurate Measurement and Cutting

To ensure a good fit, make sure the PVC pipes are precisely measured before cutting. A neat, straight cut is necessary for a successful connection.

Dry Fitting

Do a dry fit first to make sure all the parts line up and fit together perfectly before using any adhesive.

Proper Use of Solvent Cement

Apply PVC solvent cement evenly and sparingly, using the appropriate type. Overuse of glue may cause the pipe to break.

Secure Joining

To ensure that the glue is distributed uniformly, attach the PVC pipes and fittings right away with a hard twist. For a few seconds, hold firmly to establish the connection.

Allow Adequate Drying Time

Before testing the system, give the adhesive enough time to dry completely. This guarantees a long-lasting installation and stops leakage.


PVC pipe fittings are crucial to contemporary plumbing systems because they provide a number of advantages, such as chemical resistance, affordability, and convenience of installation. They also last a long time. Although installing PVC fittings is not too difficult, it is important to follow the right procedures and best practices.
