You've got the name right, it's a pipe union.  They should be easily 
available in PVC.  I know I've seen them up to 1" or 1.5" on well pump 
installations.  The 2" is somewhat unusual; might need to go to a 
plumbing supply store.

There is pipe glue just for ABS.  I forget if it's one that needs a 
"primer", so look for that.  Easily available at Lowes/HD.  Are you sure 
it's ABS?  The glue has to be matched to the plastic.  It also tends to 
be viscous stuff, and won't "wick" down into a crack well, so I don't 
know how well it would work if just brushed on the surface.
