I just use a propane torch on low to gradually heat the metal insert and then I tap it back into the plastic pipe. If the barb end of the plastic is gone, I don't worry about it.

The plastic pipe end was not molded around the metal insert sleeve. The pipe was machined inside and then the insert was inserted.
