An article in Plumber magazine titled, “Making the Connection with PEX: The Good, the Bad and the Ugly” explores the four most common types of PEX connections:

  • Copper crimp
  • Stainless steel clamp
  • Push-to-connect
  • Cold expansion with PEX-reinforcing rings

If you love PEX plumbing (specifically Uponor PEX), but you don’t use ProPEX® fittings, I’m here to tell you four reasons why you should. Trust me, it will be the easiest decision you make all day.

1.  ProPEX fittings come in sizes from ⅜" to 3", so whether you’re a residential or commercial plumber, a size is available to meet your needs.

2.  Connections with ProPEX fittings are easy to make with the use of a Milwaukee® ProPEX expansion tool. Watch the video below for a demo.

3.  A ProPEX connection is the only PEX connection that actually gets stronger over time. The shape memory of Uponor PEX pipe forms a tight seal around the fitting, creating a strong, reliable connection.

4.  Uponor PEX pipe and ProPEX fittings have a 25-year limited warranty when installed by an Uponor-trained professional, giving credibility to your name and company.
