I bought a new faucet for my galley. It has the standard 1/2" IPS theads (straight threads) for it's supply connections. All I want to do is connect my faucet to my 5/8" (ID) supply hoses with barbed fittings. I don't want any valves on the lines. Sounds simple enough but have been to Lowes and a couple hardware stores with no luck. If I find a 1/2" IPS fitting, it doesn't come in 5/8" barb. If I find a 1/2 female fitting with 5/8" barb then it's an NPT thread. I thought about buying a couple 1/2" ips vinyl supply hoses, cut the end off and find a 1/2" to 5/8" barb adapter........again no luck. Any suggestions?
