Choosing the Right SharkBite Fittings for PEX to Copper Connections

When it comes to connecting PEX and copper pipes, SharkBite fittings are the best way to go. But choosing the right SharkBite fittings can be tricky. After all, there are quite a few different types and sizes.

First, decide whether you’ll need crimp or push-fit fittings. Crimp fittings are great if you’re not worried about being able to take the connection apart in the future. Push-fit fittings are the better option if you want something that’s easier to install and remove down the line.

Next, measure the outside diameters of both pipes to help you select the right size fitting. You should always go a size up to make sure the connection is secure. Finally, make sure to choose the material that’s compatible with your pipes. For PEX and copper, you’ll need copper crimp rings or stainless steel clamp rings.

With the right SharkBite fittings, connecting PEX and copper pipes doesn’t have to be a hassle. Now you can put your DIY skills to the test!

Troubleshooting Common Problems When Connecting PEX to Copper

Be sure to use an approved PEX fitting and make sure you’re using the correct tools.
