Craftsman model 917272021 cross reference - hydrostatic vent fitting

[red73mustang]

Hey can anyone tell me who makes this model? I'm looking for the plastic hydrostatic transmissions vent tube fitting that snapped off when I was cleaning the rear diff and axles. I suppose I could source one at the local big box hardware store but I fear its an oddball 14mm size that has an o-ring.

Regards, Chet
