 Water Supply Lines/Conpression Fittings
Author: Kellibrewer (VA)

I just replaced my sink and faucet in the kitchen and the water supply lines do not reach the valves. I am using a compression fitting to bridge the gap and add a supply line, but it's leaking.

My supply line is 3/8 comp x 1/2" FIP into my compression fitting which is 5/8 OD x 3/8 OD. It's leaking at the supply line connected to the compression fitting, but it's not the fitting.

My friend says I need it to be comp to comp but I don't see that such a supply line exists. What can i do?

You need a 1/2" ips x 3/8 compression adapter. The larger compression thread does NOT fit that supply line, as evidenced by the connection NOT being tight and cocked to the side.
