What is the Exterior Diameter? of the threads?

I did not measure mine but, it fits a standard, 3 inch ABS fitting perfectly. I used it to install an RV sewer connection on my home plumbing to my septic system.

Will this hook into a 3 in cleanout?

As you can see the tabs on the fitting. They are where the drain hose will connect. Your camper must have a female fitting to screw this into, otherwise you’ll need a female adaptor for this to work.

Will a camco 39666 hose lock on to this fitting

Yes, the Valterra termination adapter should fit with your hose. It is the standard 3" bayonet size.

Does a version of this exist with a female thread end?

Sure if I have a reliable answer
