"What type of glue (glue?) should swim have used to remain vacuum, temperature and chemical safe?"
Epoxy is good for many chems and new versions are good to 600F. Look for Novolac type Here are a couple links if I did it right. You won't find this stuff in the hardware store and it ain't cheap. For coating parts use the no filler or solvent Novolac. Also PTFE tape used to mold the glue provides a temporary virtually impervious barrier.

Make sure you sand the surface for adherance and don't put on any thicker than the spec.
