Obsolete Versatile 3000 sprayer, doesn't seem to be listed on CNH parts.  It has a black PVC elbow on the bottom of the chemical inductor tank that is broken.  one end is 1 1/2" barb for a hose.  The other end has a small flange with a big nut that screws onto the tank, similiar to a swedged  tubing type fitting, only big and the flange is molded right onto the elbow, not swedged.  Is this fitting unique to this machine, or do flanged PVC fittings exist anywhere else?  If I knew what to call it, I could do some more searching.  Definitely doesn't exist in the plumbing department of the local hardware store.  I expect other sprayer brands must use the same tank and fittings?
