It Is Important To Know How To Install Poly Pe Fitting

  • The flexible nature of polyethylene pe fitting allows it to be used in colder climates -- where it will not crack -- and in situations where rigid pipe would require multiple elbows to make complex turns. Unlike other plastic piping, poly pipe connections do not use glue to solvent weld pieces together. Instead, two specially designed pp fitting types seal poly connections using friction. Both types have specific installation instructions to ensure they hold connections together under pressure.

    Barbed Poly Fitting Installation
    Cut the required length of tubing from a polyethylene pipe roll with a sharp-bladed utility knife. Make sure the cut is straight. Slide a hose clamp over the end of the pipe. The hose clamp size must match the size of the tubing.

    Dip one end of a barbed poly fitting in a water-based lubricant. Hold the lubricated fitting in your dominant hand and the cut piece of tubing in your other hand.

    Forcefully push the fitting into the end of the tubing as you twist the fitting back and forth.


    Slide the hose clamp toward the fitting until the end closest to the fitting is 1/4 inch away from the end of the tubing. Turn the clamp screw clockwise with a 5/16-inch nut driver to lock the fittin
