    I'm looking for a satin nickel p-trap with an extension pipe that has an opening (similar to a garbage disposal tee) to accept an HVAC condensate drain line.

    The pvc ones are easy to find but does anyone have any experience with a decorative one for a custom home? It will be visible.

    The condensate line must discharge into an air gap.

    Tailpipe on P trap

    I realize the condensate line must discharge before the u-bend but I'm looking for a tailpipe extension that has a connection similar to that found on pipe from a garbage disposal. These I can get in pvc. I'm looking for a metal one.

    Your better off sticking with plastic as condensate water is acidic and will eat through metal.

    I'm not sure you understand what is meant by condensation lines draining into an air gap. This means it can not connect solidly. I drains similar to a washing machine, just on a smaller scale. Just for clarity, what you call a U-bend is commonl a P trap.

    Thank you. Do you have a web link for Eastman? No luck on my google searches.

    Cheers

    You can not dump the condensate line into the fitting you want to use.

    Condensate must drain into an indirect waste using an air gap or air break.

    802.1.5 NonPotable clear water waste

    Where devices and equipment such as process tanks, filters, drips and boilers discharge non-potable water to the building drainage system, the discharge shall be through an indirect waste pipe by means of an air break or an air gap

    I don't know where you get your information, but in this area MOST A/C condensate lines DO disharge into a branch tailpiece and NONE of them have "air gaps". Get a chrome 1 1/4" threaded brass branch tailpiece, (most plumbing and big box stores have them), and then "rub" it with steel wool to give it the satin stainless steel look.
