What is a pipe connector called?

The term "pipe connector" is a broad category that encompasses various types of fittings and devices used to join or connect pipes. The specific name for a pipe connector depends on its design, function, and the method of connection. Here are some common types of pipe connectors:

1. Fittings: This is a general term that includes elbows, tees, reducers, couplings, crosses, and many other shapes designed to join, branch, or redirect pipes.

2. Couplings: Used to connect two sections of pipe or to repair a damaged section. They come in rigid or flexible designs and can be threaded, compression, or flanged.

3. Adapters: These are used to connect pipes of different sizes, shapes, or materials, such as joining a copper pipe to a PVC pipe.

4. Reducers: These are used to connect pipes of different diameters, reducing the size from one end to the other.

5. Flanges: Flanges are flat metal rings used to connect pipes, valves, pumps, and other equipment. They are bolted together to form a seal.

6. Union: A union allows for the disconnection of pipes for maintenance without the need to cut the pipe. It consists of three parts: two ends with male or female threads and a middle sleeve.

7. Compression Fittings: These are used to join copper, PEX, or CPVC pipes using compression nuts and sleeves to create a watertight seal.

8. Push-Fit Fittings: Also known as quick-connect fittings, they allow for fast connections by pushing the pipe into the fitting, where a compression ring forms a seal.

9. Solder Fittings: Used with copper pipes, solder fittings are connected by soldering the fitting to the pipe to create a permanent, watertight joint.

10. Clamp Connectors: Hose clamps or band clamps are used to secure hoses or pipes to fittings, or to join flexible pipes together.

11. Butt Weld Fittings: These are used in high-pressure and high-temperature applications and are connected by welding the ends of pipes and fittings together.

12. Threaded Connectors: These are fittings with threads that screw onto the ends of pipes to create a seal. They are commonly used in iron, steel, and brass pipes.

13. Barbed Connectors: These fittings have barbs that grip the inside of a flexible pipe, such as PEX or polyethylene, to create a secure connection.

14. Push-on Fittings: Similar to push-fit fittings, these are used with plastic pipes and are simply pushed onto the pipe end to form a connection.

15. Electrofusion Fittings: Used with polyethylene (PE) pipes, these fittings are connected by passing an electric current through the fitting, which melts the fitting and the pipe, creating a weld.

Each type of connector is designed for specific materials and applications, and the choice of connector depends on factors such as the pipe material, the pressure and temperature of the system, the desired permanence of the connection, and the ease of installation and maintenance.
