Repairing Cracks in Female Threaded Fittings

They do make abs glue, you should be able to get it at a plumbing supply or pipe and valve supply. Just look for a yard full of big pipe, and fire hydrants and stuff. You can buy it there for sure, if not at HomeDepot.

I just did the same thing this past weekend. Epoxy is definitely the route to go. It's fluid and seeps into all of the gap and doesn't care what type of material you are bonding. As an extra step though, I removed the pipe and placed two sticks 3/4"x3/4" about 5 " long inside the edge of the cracked female fitting. If you place a bolt between the sticks and use a clamp on the opposite ends of the sticks you can gently spread the fitting apart and force epoxy in the opening. (Again... careful... don't want to overspread) Loosen the clamp remove the sitcks and finish with a hose clamp. When the glue starts to set pick the excess out of the threads with a small knife. Teflon tape and reassemble. Eliminates the risk of permanently gluing the pipe in place.
