Our boat has 7/8" heater hose from the heat exchanger to the water heater. I need to replace them as I am installing a new water heater, and I am having difficulty finding 7/8" hose barb fittings. Ideally I'd like to go from 7/8" hose to 1/2" male npt, but I could come up with other solutions if I could find any 7/8" barb connections. Anyone know of a source?
