Copper pipe is a versatile plumbing material, being antimicrobial, corrosion-resistant and easily cut to length and joined using copper pipe fittings. But do you know how to choose the right fittings?

Types of copper pipe fittings

There are many different types of copper pipe fittings and specialists such as watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems stock a wide range to suit all purposes.

Examples of different types of fittings include elbow joints, couplings and caps, all of which have a distinct purpose and if used incorrectly, you run the risk of leaks and unhappy customers.

Selecting for purpose

When selecting copper pipe fittings, you must first determine the size of the copper pipe that you need to join. Most copper pipes come in one of three widths – either 15mm, 22mm or 28mm diameter.

Next, consider why you need a fitting. Are you shutting off an unused section of pipework, joining two pipes in a straight line or connecting pipes together at an angle?

What is the purpose of the pipework? Will it be to direct clean water in a residential plumbing application or are you installing underground service pipelines?

Once you have established the size of your pipe, the reason why it needs to be joined and the environment in which it will be used, you can select the appropriate fitting for the job. For example, if you want to connect two lengths of 22mm pipe in a straight line for a domestic plumbing job, you will need a 22m coupling.

If you are unsure, always ask an expert before you buy.
