Things You'll Need
Instructions
Take the PVC pipe to an outdoor area, or at the very least a well-ventilated workshop. Fumes from burning PVC pipe are toxic, so you want a place where the fumes can escape if you apply too much heat.
Place the PVC pipe onto a non-flammable surface.
Plug your heat gun into an electrical socket and hold the muzzle about an inch away from the portion of the PVC pipe you want softened.
Activate the heat gun and move the muzzle back and forth slowly across the section of pipe. It will take about a minute for the pipe to soften enough for you to actively shape or bend it.
