Since you know the Valterra fitting will be the right fix, just you have lead time issue, not sure where you are buying them from.
See here for a few options.
RV upgrades, they show 14 in stock, $3.00 plus shipping https://www.rvupgradestore.com/Valte...-p/89-8290.htm
They are in Ohio. Call and see if they are shipping from Ohio or some other drop ship warehouse. I can't see 2 weeks to ship from Ohio to Maine.
Amazon, $8 and free shipping, they say 4 to 5 days https://www.amazon.com/Valterra-T102...074093&sr=8-19
Etrailer $6.22 plus shipping. 3 days to Ohio, not sure on Maine https://www.etrailer.com/RV-Sewer/Va...xoCFHkQAvD_BwE
I'm not sure a hose clamp, worm drive clamp, is going to compress that dump hose female flange before the strips out the worm drive clamp.
