In the realm of plumbing, CPVC (Chlorinated Polyvinyl Chloride) pipe fittings play a pivotal role in ensuring efficient and safe water supply systems. Understanding the various CPVC pipe fitting names is crucial for plumbers, DIY enthusiasts, and anyone involved in pipework. This article aims to provide a comprehensive guide to CPVC pipe fitting names, their uses, and how to choose the right fitting for your needs.

Understanding CPVC Pipe Fittings

CPVC pipe fittings are designed to connect, direct, or control the flow of water through CPVC pipes. They are available in various shapes and sizes to accommodate different pipe diameters and applications. The most common CPVC pipe fittings include elbows, tees, couplings, and caps, among others. Each fitting serves a unique purpose in a plumbing system.
Common CPVC Pipe Fitting Names and Their Uses

Familiarizing yourself with the following CPVC pipe fitting names will help you navigate the world of plumbing with confidence.
Elbows

Elbows are L-shaped fittings used to change the direction of a pipe. They are available in 90-degree and 45-degree angles, with the latter being used for making turns in confined spaces.
- 90-degree elbow: Used for making 90-degree turns in pipe runs.
- 45-degree elbow: Used for making 45-degree turns in tight spaces.
Tees

Tees are T-shaped fittings that allow for the branching of a pipe into two directions. They are commonly used in plumbing systems to connect pipes perpendicularly.
- Straight tee: The branch connection is in line with the run of the pipe.
- Cross tee: The branch connection is perpendicular to the run of the pipe.
Couplings

Couplings are used to connect two lengths of pipe end-to-end. They are available in various sizes and styles, including slip couplings, solvent-weld couplings, and threaded couplings.
- Slip coupling: Used with CPVC pipe solvent cement to create a permanent connection.
- Threaded coupling: Used to connect threaded CPVC pipes.


















Caps
Caps are used to seal the end of a pipe, preventing water from escaping. They are available in various sizes and styles, including slip caps and threaded caps.
- Slip cap: Used with CPVC pipe solvent cement to create a permanent seal.
- Threaded cap: Used to seal the end of a threaded CPVC pipe.
Unions
Unions are used to connect two pipes with the ability to disconnect them easily for maintenance or repair purposes. They consist of two halves that are joined together with a nut.
Valves
Valves are used to control the flow of water through a pipe. They are available in various types, including ball valves, gate valves, and check valves.
- Ball valve: Used to control the flow of water with a quarter-turn of the handle.
- Gate valve: Used to start or stop the flow of water by raising or lowering a gate.
- Check valve: Used to prevent the backflow of water in a pipe.
Choosing the Right CPVC Pipe Fitting
When choosing CPVC pipe fittings, consider the following factors:
| Factor | Considerations |
|---|---|
| Pipe diameter | Ensure the fitting is compatible with the diameter of your CPVC pipe. |
| Application | Choose a fitting that suits the specific needs of your plumbing system. |
| Pressure rating | Select a fitting with a pressure rating that meets or exceeds the requirements of your plumbing system. |
| Temperature rating | Choose a fitting that can withstand the temperature of the water in your plumbing system. |
Installing CPVC Pipe Fittings
Installing CPVC pipe fittings involves several steps, including measuring, cutting, deburring, cleaning, applying primer, and applying solvent cement. Always follow the manufacturer's instructions for the specific fitting you are installing.
In conclusion, understanding CPVC pipe fitting names and their uses is essential for anyone working with CPVC pipes. By familiarizing yourself with the various fittings and their applications, you can ensure that your plumbing system is efficient, safe, and long-lasting.
