Joining PEX – Cinch Ring Method

Using PEX tubing and fittings

Working with PEX tubing and fittings is by far the easiest plumbing connections to make. There are a multitude of different types of PEX tubing and fittings on the market but all of them will do the same job as long as they're rated for potable water.

Homeowners should consider using the cinch ring method of joining PEX, because the tool is relatively inexpensive to buy and it will work on different sizes of pipe.
