Bulkhead issue

[lostmyz]

I have a 3/4" bulk head that I am using for my PICO build. I went to home depot today finally to get my plumbing stuff.... I got my pool/spa flex hose, but when i went to get some fittings for the bulk head to expand it up to 1.5" to accommodate the flex hose....i ran into an issue...

I tried to thread a 1" pvc coupling with an expansion to 1 and 1/4 but it would get on.... Where can i get the proper fitting...

I hope this makes sense lol

Naughtons has alot of speciality fittings or SanPlumbing supply on Grant and I-10. Thats where I got 1" Y's before.

the inside is a slip.... im running my return line through the drain....

and my return line is 5/8" OD and 1/2" ID

Bulkhead is 1-1/4 OD and 1-1/8 ID

i don't want to make the inside diameter too small that the return won't fit an allow flow. I will be using 1-1/4 ID PVC Drain hose..... technically I could just sleeve the OVC drain hose over the bulk head and use a hose clamp and be fine OR makeshift some adapater and use vinyl hosing from ACE (heat it up and slip it over the end of the bulkhead to make a tight fitting like a barbed hose adapter sorta... (if that makes sense) I mean the line is gravity fed it doesnt need to be glued.... its not like water is going to travel down gravity and than trek back up over the bulkhead threads while its sitting perpendicular to the floor
