Different connections

There are different methods and fittings that you can use and source from specialist sites such as These include:

Compression fittings

These are easy to use and are a cost-effective solution. Compression copper pipe fittings are made up of a fitting body, a ferrule, and a threaded nut. You simply slide the ferrule and nut over your pipe before inserting it into the fitting body. Finally, just tighten the nut.

Push-fit fittings

These are convenient and quick to use and don’t need any sealant tape or tools. You just need to push the rubber O-ring into the fitting to seal the pipe.

Flare copper pipe fittings

This type of fitting is secure and strong. The cone-shaped end fits into your fitting but you will need sealant tape or pipe dope and a flaring tool.

A flaring tool is needed to expand the end of your pipe to create the cone shape. You have to apply some of the tape or dope onto the flare before you tighten up the nut using a wrench.
