I'm getting ready to replace my kitchen sink faucet. Currently the supply lines are rigid steel, but I've heard that they're tricky to work with, compared with flexible braided lines. On the other hand, they seem less likely to burst spontaneously (unless I screw up the connections, of course). Any thoughts as to which option would be the better bet? TIA!

I use stainless steel flex lines all the time just remember long sweeping turns so you don’t kink them typically they are good for 10 years

Just install new stainless flex lines every time you install a new fixture or dishwasher. They will likely last as long as the fixture.

the stainless braid is merely a 'cover' for the internal plastic tube

the quality of the interior tube varies GREATLY


IMO: 'split the difference' and use PEX supply tubes as you ALREADY have and can reuse the required 'shank nuts'

I think rigid tubings look better in exposed install like pedestal sinks but with kitchen it's inside a cabinet.

I will wait till you get the faucet before deciding on the tubings because many newer faucets come with braided hoses already integrated into faucet shank that I don't think it's easy to change out.

Thanks to everyone who replied! I appreciate it very much.
