    I recently purchased two lavatory faucets for my master bedroom.

    When looking at what length of supply lines I would need I noticed that this particular faucet doesn't have the flexible supply's coming from the main - as was the case of my kitchen faucet and another faucet I've done recently.

    This one simply has threaded tubes coming down from the hot/cold. So my question is does the typical steel braided supply lines (i.e. watts found at Lowes) work with this type of connection?

    The instructions for these state that the user must bead the supply tube when using the compression fittings included with the faucet.

    Are there certain faucets which can't use the flexible steel braided supply lines with the rubber compression seal inside?

    Thanks -

    Most if not all faucets are set up to take 5/8" IPS threaded connections. EDIT: I meant 1/2"


    There are some faucets that still use the soft copper 3/8" stubouts and that takes a stainless steel extension line to connect to, which is 3/8" by 3/8".

    For some reasons, faucet manufacturers still often include a 1/2" nut, flat washer, and rubber cone washer. These are for use with plain 3/8 copper tube. You muse bead the end of the tube to prevent it from pulling out.

    I honestly never used this kind of supply. It just isn't done around here.

    Any flex supply with 1/2 IPS connector will fit your faucet./

    I don't know what I was smoking when I typed 5/8". ????

    faucet

    I have no idea what you are trying to describe, but some of the new Delta faucets come with a long 3/8" pex supply tube which have preassembled compression nuts. If they are too long, then they say you have to use the supplied compression rings to make a seal. The only time I have heard of "beading" a tube was when using cone washers on straight tubes, and that was to keep them from slipping out.
