I have a 1" barb male thread fitting that is screwed in to a PVC tee.

as per the other posts....I quit doing "male metal pipe threads into
female PVC fittings".

I only cracked one but that was enough. Now its male PVC into metal.

But to the problem at hand.......you could try the one of the various
"goops" being suggested

compatible with PVC http://www.devcon.com/products/produ...2&familyid=439

or since (imo) the fitting is probably cracked.... to fix the real
problem.

Screw the metal bard fitting into a metal coupling, screw a PVC short
nipple into the coupling. Prime, glue & screw the PVC/metal assembly
into PVC tee. Allow several hours to cure & you should be good to
go.
