    It is. Sorry I could not post earlier but I just got back from celebrating Aunt and Uncle's 40th anniversary.

    I looked it up and you are right..1/2" tapered thread.

    Strange AA could not help you...did you talk to Jeremiah? I have the same pump and he knows that thing inside out and they are an authorized Robinair service center.

    Your 15550 is different than mine than. I have noticed that the older Robbie's like mine specs are a little different
    and the diffs don't show up on the specs sheets.


    For instance, my sight glass has a gasket and threads in...newer models are pressed in. My intake is 1/2" tapered.....Sorry I could not help.

    No worries, I appreciate the help. This is the full reply email that I just received from robinair when trying to get the specs. What a joke!

    "This pump come from China and they do not give us the specs on the fitting that you are asking about, the best thing i would be for you to do is take it to a hardware store and try to match it up that way."

    WTH????? Robinair is owned by Bosch now?

    I just talked to Jeremiah at AA Hydraulic. Yours is a China made pump and there is no uniformity to the parts, every pump coming off the line could be any size intake.

    But Jeremiah said that most are 1/2 coarse Tapered pipe thread.

    Mine was American made and and has a straight thread and an O ring to seal it (yeah, I screwed up).

    I would suggest a coarse thread brass nipple And an adapter from JB or YJ and a tee from them also.

    Jeremiah also said this is the consequences of buying a very inexpensive pump (cheap).

    Try to stick with an American made Robbie. Jeremiah probably has some re-fabed or abandoned Robbies you could pick up cheap. This is my suggestion not his. If you want his number email me (any body).
    Add at gmail to my name.
