motor aid fittings

[fl_bluebird_1983]

Does anyone know where to get fittings for the heater hose. I'm trying
to replace my water heater, and one of the fittings that splits the
heater line (Motor Aid) broke, tried to braise it back together but 23
year old pipe doesn't like to go back together. It is a 1" y connector
that reduces from 1" to 1/2" the 1/2" goes to the motor aid. Napa
doesn't carry them, it think they are brass/bronze.

Thanks
