I went to replace my kitchen faucet only to be stopped in my tracks by a mismatched setup. The old faucet uses flexible copper supply lines which are brazed into the faucet end and have a male connector on the other end.The female connectors off of the PEX will not reach the standard style faucet with two separate inlets.I have not been able to find a replacement faucet that matches what I have. I would really like to find an exact match so I don't have to cobble the system together.I would be happy with a short extension hose that has a male on one end and a female that would attach to the faucet on the other.Any help would be appreciated!

You already have a cobbled mess, RV manufacturers do that.Cut the PEX pipes down low, install shutoff valves, then run standard faucet supply lines like they do in a properly built house.

Buy the faucet by the look and function above the sink.Then get what you need at Home Depot and connect.

I don't like what you have now because if there is ever a problem with the supply line the entire faucet has to be replaced. If you try to attach a supply line and accidentally twist the copper it's all over.I'd much rather have the short inlet pipes which are very sturdy. I agree with the idea of buying what works well for you above the sink. The below stuff is one time. The above stuff is every day.

We discovered when searching for a replacement faucet for the toyhauler that most faucets, especially the more expensive ones, are coming with the attached water lines. We spent a lot of time trying to find one that just had the short hard line that attached to a water line.

From my experience it assumes household water pressure, not the 40psi you find in an RV. Sorta like needing bigger cable for 12v.
