Q: Can you connect a flexible faucet supply hose directly to a “7/16inch & 1/2inch slip joint” outlet?
What would the supply hose specification be?
(For example, you connect a “1/2inch OD Compression” ended supply hose to a “1/2inch Tube OD” stop valve outlet, and you connect a “1/2inch FIP” ended supply hose to a 1/2inch straight or tapered male iron pipe thread. In both cases you depend on the cone washer and nut that are integral to the supply hose)
