If the faucet is a Hansgrohe the hose ends should be 3/8". If they are straight ended with no nut on the end they will connect using a 3/8" nut and ferrule just the same as an old style soft copper supply tube. If there is a nut on the end of the hose it should be 3/8" to connect direct to a 3/8" service stop. If you need further help feel free to contact me at Hansgrohe Tech. 1-800-334-0455. Press 2 for Tech and ask for David Scarborough. I'll be happy to help.
