Sched 40 pipe 2"

Spa problem. Cut between 2 PVC fittings to remove a cracked part. No pipe was showing, so I cut between the 2. This means no pipe showing to glue the new fitting. The remaining fitting is a 5 port flange that is not cracked.

This is really locked in there. To change that as well would mean re-piping half the tub, plus a lot of insulation stripping. Is there a "repair fitting, coupling, elbow " that would go INSIDE the remnants of the 2" pipe, instead of outside? Maybe a different diameter pipe? A pipe Hog wont work because of all the pipes from another manifold are in the way.

There are "inside" couplings, but good luck finding one. Normally it would be a special order and you would have to buy a "boxful" of them, but try here http://stores.drainageproducts.us/-strse-1381/PVC-Internal-Coupling-Schedule/Detail.bok
