What does a compression fitting primarily connect?

A compression fitting primarily connects two sections of pipe. This type of fitting is designed to create a secure, leak-proof seal between the ends of two pipes. It accomplishes this by utilizing a compression ring that, when tightened, compresses against the pipe ends, thereby providing a strong and reliable connection without requiring welding or soldering.

This characteristic makes compression fittings popular in various plumbing applications, as they allow for ease of installation and removal, making them versatile for both permanent and temporary setups. The design is specifically made to handle the pressure of fluids flowing through the pipeline, making it an essential component in plumbing and gas systems.

Other options, such as connecting a gas meter to a pipeline or a regulator to a service line, may involve different types of fittings more suitable for their specific functions. A valve connected to tracer wire typically deals with electrical connections rather than fluid connections, further distinguishing compression fittings' primary role as connectors between two pieces of pipe.
