Need help retrofit skimmer cup

[reeftilldie]

Does anyone know where can i get this drain plumbing parts fitting for my skimmer cup?
I'm planning to drill and add a draining hose to my skimmer cup, unfortunately this is the reef octopus 110 and side drilling is my only option. I can't add uniseal because the smallest size of uniseal is 1/2" and its too big for my skimmer cup.
I'm looking for somethings like 3/8? or 1/4 if possible.

Any suggestions anyone?
Thank you

Have you tried BRS or CoralVue? That's where I'd start.

Seems like I answered this once a few days ago....is this a duplicate question or did I never hit "Post"??

Jehmco has lots of oddball stuff. I'd try them.

Why drill the side instead of the bottom?

Yeah, email or call coralvue

Those kind of fittings can be had at big box hardware stores in the plumbing isles. 1/4" or 3/8" should work. Drilling the bottom flange on the cup should be doable, but depending on its width.
