Hmm, I guess they quit carrying them in the larger sizes.  Home Depot used
to have both socket weld and compression unions for PVC in 2"; but 1.5" is
the biggest I see on their web site.  

But MMC has them in 2" socket weld.

Or I see a box of 5 compression unions on eBay :
Might be you could talk the seller into a smaller quantity, or resell 4 of

Or, use a socket weld to NPT adapter, plus one of these :

JB Weld is supposed to stick to ABS, tho I've not tried it.  My SS pool
filter is repaired with JB Weld reinforced with fiberglass cloth and it's
held up for several seasons.  When I tried to repair the PVC chlorinator
with unreinforced JB Weld, it split open again in a few months; but adding
the cloth seems to make the difference.
