Neptune Cor 20

What size and type of fitting do the inlets of the Cor 20 and 15 have? I’m looking to run them externally. The specs on the websites are not clear to me. Thanks

You know, you think I would know since I own a pair of Cor 15's. Great pump by the way. I started with one for a return on my 210 gallon then after watching some BRS videos one of them suggested using the same pump, if possible, for a skimmer and use has a backup. Made sense to me so I recently brought another Cor 15 online just for that. Glad I did. Anyway, doubt I can answer your question but here is some text from one of the pages I read if it helps any.

Included fittings

Both the COR-20 and COR-15 come with all the fittings necessary for most aquarium configurations (0.75″ output, 1″ input). A 1.25” union for the output also is included, allowing you to connect the pump in a way to produce as little head loss as possible.

What’s required

Plumbing fittings, hose, pipe, etc., and some basic knowledge of plumbing. For the COR-15, you’ll need any Apex System with an available 1LINK port.

What you get with the COR-20

COR pump, COR-20 pump driver, 100W 24VDC power supply, power cord, 1.25-inch PVC union (Slip->BSPP), 1-inch slip fitting, 0.75-inch slip fitting, and a 3-foot AquaBus cable.

What you get with the COR-15

COR pump, COR-15 pump driver, 1.25-inch PVC union (Slip->BSPP), 1-inch slip fitting, 0.75-inch slip fitting, and a 6-foot 1LINK cable.
