Tips for Joining Copper Pipe with Compression Fittings Tips for Joining Copper Pipe with Compression Fittings

If you wish to connect a copper pipe to another pipe or to a fixture, but can't solder the connection or want to remove this connection, one of the most simple ways to make this connection is to use copper pipe compression fittings. Follow the tips below as you work to ensure a successful project.

Cutting Your Copper Pipe

Before connecting your copper pipe, you will probably need to cut the pipe to fit. This may not be as easy as it seems: any attempt to cut a copper pipe with a saw could bend the soft copper walls of the pipe and make it impossible to connect to another pipe or to a fitting. To cut a copper pipe without creating a burr on the end or without bending it, use a pipe cutter.

Compression Coupling Components

Components of a compression coupling include a nut, a ferrule and a valve. To work properly, these components must fit together in a precise order. When fitted on the pipe in the right configuration, the compression nut will slide down the pipe to the valve fitting where it can be screwed onto the fitting.

Tightening the nut squeezes the ferrule against the tube, making a watertight connection. To help avoid leaks in these connections, you can wrap Teflon tape around threads of the fitting.
