    Default Kohler shower hardware....

    Folks,

    Recently completed a total re-do of a small bathroom.

    The wife requested a shower head with more "Force" (Interpreted as higher flow velocity. Shower flow volume is spot on to the 2.5 gal/min standard.)

    The Kohler parts are bass ackwards to most of the shower hardware that I have seen:

    Shower head: K-10590-AK-BN PDf files show female connection: Mine is male: Threads are undersize for 1/2" pipe thread.
    http://www.us.kohler.com/webassets/k.../1040132_4.pdf

    Shower outlet: K-9511-BN PDF files show male connection: Mine is female: Threads are undersize for 1/2" pipe thread.

    http://www.us.kohler.com/webassets/k...n/087753_4.pdf

    I have talked with Kohler about these problems. They have promised to get back to me......

    Question: Does anyone make a SS short nipple that has the undersize male threads on one (or both) end?

    Are there any other easy/inexpensive solutions to changing the shower head?

    TIA,

    Rog

    Looking at the spec sheets everything looks fine.

    1/2 NPT, which is standard stuff.

    I see that the K-9511 has two outlets, a male 1/2" pipe thread and a 1/2 hose thread with diverter.

    Something is not kosher. Kohler would not make items with the "wrong" male thread, AND then also make them undersized. EIther you have some metric stuff, or it is some company's copy of a Kohler design. As far as "undersized" goes, there would not be an "standard" for an undersized thread so it would have to be made to match what you have.

    Yeah,

    I am scratching my head too....

    The K9511 shown above is not the same as mine. (Mine has a Female connector for the shower head.)
