Assuming you’re referring to the DrainMaster nozzle end, Newell actually has made a connector just for that purpose.

That's interesting.  Any photos of it?

No, sorry…I was shown one a couple years ago and keep forgetting to grab one.

I simply use what I’ve always had…a hose clamp and standard hose without any end. Slips over the nozzle and twist the clamp to secure.
