Part # 9170-18
Manufacturer Code 417-4000
Dimensions 1-3/4" X 1-3/4"
Tailpiece, 1 1/2in (91431050)
On the Pentair website the part number I need is 350093, but it looks just like your part number here (91431050). The Inside dimensions of my tailpiece is just a little over 1-1/2" by like 1/16". My Pentair Pump Model is 340039 and I need the tailpiece that goes down into the pump. Is this the correct part?

Hi Michael, Yes this should work as a replacement for the Pentair 350093 tailpiece.
