Help plumbing up overflow

[ben310135]

All, I am hoping someone can tell me how I need to plumb the overflow in my drilled 110 aquarium.
I have a question about how to connect the overflow plumbing in my tank to the 1 inch flex tubing of my sump and the overflow plumbing is 1.5 inches. I have attached a picture of the end of the overflow plumbing. Any help would be apprishiated

You would need a Bard fitting on one end and a slip on the other. Common at most Hardware stores.

What would the slip be used for?

Does anyone have any pictures of their plumbing for their overflow ?

Sure, but I'm not sure how much good it'd do you

My setup is quite a bit different from yours

The end of your overflow plumbing has a 1.5" slip fit bulkhead, if I'm understanding right, and your sump has an inlet of 1" flex tubing. If that's the case, you need a 1.5" slip to 1" slip reducing bushing, like this:

and a 1" barb fitting, like this:

A bit of 1" flex pipe, a few 1" nylon clamps, and you're all good
