800 992 9898 ask for Jeremiah.
They are AA Hydraulic Dervice. An authorized Roinair servicer.
I got my tee from them. Was a little pricey but I know I got the right part.
I have a robinair 15500 that im looking to up size the tee for 1/2" hoses. Any one know what size and thread type fits inside the vacuum pump? I thought it was npt, but might be acme?

Hey hvac5646- Im in Livonia enjoying the heat wave. Just checked my yj hoses, the're 1/2" flares.
I called aa but they were closed. Ill try again wed. Thanks for the help!
I remember going through this. What size thread goes directly into the pump.
Hi George, I have a robinair 15444 VacuMaster & the thread into the vac pump is 7/8"ONO which is Dash 14 = 7/8"UNF &14TPI, parallel thread with O Ring champher in the pump. Cheers - Leigh
I called robinair product support and they couldnt find the inlet size- go figure. Same with aa. I ordered a 1/2" npt 1/2" flare tee off fleabay for 6$ to give a try. If it doesn't fit, no big loss.
Thanks Leigh. It looks like 15500 is smaller than 7/8.
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.
Well its not 1/2" npt. Its to big.
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.
