Check with Dupre Products, I think they supplied the dump valves for our coaches. www.dupreproducts.com
You can always call Newell, they do stock the Dupre products.

bill, our vintage coaches have the dupree valve and fittings. i use the dupree fittings on a rhinoflex hose. i also used a dupree fitting on a very short rhinohose with a valterra male on the other end for my portable macerator. it would also work for using a regular velterra hose.

I checked with Dupree and they do NOT make an end adapter to screw into the ground dump. I have to dump and store my hose because I don't have an end fitting. What do people use at the end of your Dupree hose to be able to leave the hose in place while camping?

Dupree hose? I have a rhino flex attached to the Dupree elbow on one end and the standard attachments on the other.

I modified a Dupree fitting and attached a regular RV hose elbow. In a few day when I am settled in Elephant Butte, I will take a photo and post it. It would be instructive if others would post a photo of their rigging.

OI think I can do this from my phone.

This is what came with my coach, Dupree sewer hose. They just don't make a ground end

That looks suspiciously like a Rhino flex hose or something very similar. You might want to buy one of the Rhino connectors and see how well it attaches.

Here is my solution to convert from Dupree to Valterra... I purchased a Valterra 5" clear bayonette adapter, and cut off the needed end. It was a perfect fit to slide over the Dupree end that usually has a hose clamped on. Now the RhinoExtreme hose kit just twists on right out of the box using the Valterra connectors.
