Use a heat gun, spread the heat around until it starts to get limp then you
can bend it without collapsing.

Have 90 degree one inch diam. grey plastic tubing 90 deg. bend.

Want to bend it some more; hopefully to 180 degrees (or close to that)
to make shape of a 'J'.

Any suggestions. Heat gun? Flame? Oven? Also will it tend to flatten
as metal pipe does when bent further?

If this doesn't work could I use something else; that newer PEX water
piping for example?

Help/advice appreciated. TIA
