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
