There are a variety of reasons to bend or mold PVC pipe. Craft projects, green houses and lawn ornaments can all be made using molded PVC. Molding PVC to form a curve or a bend can save money by eliminating the need for one or more fittings.

Use heat to bend PVC for seamless curves.

Things You Will Need

  • PVC pipe
  • PVC caps
  • Sand
  • Heat source
  • Leather gloves
  • Cold water bath

While the process of molding PVC is not difficult, there are some tricks to help ensure that the results are worth the effort.

  • Cap one end of the pipe and tightly pack it with sand. Cap the other end.

  • Put on leather gloves for protection and use a heat gun or other high heat source to heat the PVC until it is soft. Keep the PVC at least an inch and a half from the heat source so it doesn't burn.

  • Slowly bend the PVC into shape. The sand will ensure that the pipe stays round and doesn't kink or flatten.

  • Hold the PVC in shape until it cools. Dip it into cold water to speed the cooling time.

    • Tip

    To create the same bend over and over, make a jig.

    Warning

    Never leave flames or heat sources unattended. Work in a ventilated area.
