Careful when heating PVC... It gives off nasty fumes

I can confirm that Mario's method is an excellent one.
In addition, if you want to restrain the diameter, use a glass jar into you push
the elbow in after hot air heating it. Don't use a flame, it may damage the PVC
and/or give a poor result. You also may turn a piece of metal tube at the
required dimension. Keep in mind that in this case the metal tube shall also be
heated otherwise it will be difficult to restrain a plastic tube being cooled by
the cold tube during the operation.
I used these two methods a lot of times and it always worked. If the result
isn't what you wanted, heat it again and it will almost recover its original
shape :-)
It also works well on nylon tubing. I purchased 3/8" tube for my compressed air
distribution and it happened to be 10mm. My fittings were 3/8". Instead of
wasting time with a new order, I restrained the nylon tube using the second
method. No leak @ 8 bars for at least12 years.

Better still. Turn a wood dowel to the desired ID and use it to expand the PVC after slightly heating it
