    Default O-ring supply connections on lavatory faucet -- convert from braided hose to 3/8 tube

    Hi,

    I have a new Danze faucet I want to install on a wall-mount sink. The faucet came with braided supply lines. I would like to replace them with conventional 3/8 chrome hard line since the plumbing is exposed.

    This is one of the supply hoses. On one end is the standard 3/8 compression style fitting with an O-ring; on the faucet side is this:

    Is this a standard fitting?

    Shown with 3/8 tube for scale:

    The threaded portion is 1/8 NPT or nearly so (I can't tell if it is actually tapered or not).


    I tried asking Danze how to do this and they sent me a new set of supply hoses and a couple 1/2 IPS to 3/8 IPS reducers. An "A" for effort, but no so good on the reading comprehension.

    You will need to use the supplied braided hoses.

    There is no way to push a solid riser into a threaded connection and get a seal.

    More and more faucets are being sold this way.

    Do the faucets you've seen use the same double O-ring connection?

    I haven't tried to interchange them.

    Every manufacturer uses his own method. Some use one "O" ring, some use "push on" connections, and others use braided hoses with conventional size connections. But, except for the last one, there is NOTHING that will replace the original connector. If appearance is a factor, then you have to buy a faucet which either has good looking connectors or can be converted to something else. Most DIY faucets will have a "fool proof" method of connecting and that usually means proprietary and not changeable. Even if it were 1/4" ips, which it looks close to, without some way of sealing with "O" rings it would leak.

    Ok, thanks Terry and HJ. It is useful to know there is no typical way to do what I want. Now it's a challenge

    Oh! Oh! There should NOT be a challenge since you should use the supplies as furnished. IF you accept the challenge, do not come back later and ask, "What can I do now? I damaged the supply lines and now nothing will work."

    Thanks for your concern. Maybe I'll just return the faucet. The lines aren't long enough to use as-is.
