The CPR Return jet offers a fast and convenient solution for plumbing return lines up and over the rim of the aquarium. This is a great option when drilling the glass for a bulkhead is not practical or possible. The U-shape of the return jet allows the assembly to simply hang right on the rim with no special plumbing required. Just pick the Return Jet sized for the flexible hose you are using from your return pump, and attached to the molded barb, and you're set! The return side will sit below the water surface to avoid excess turbulence and splashing, and a custom ball and socket connection on the return nozzle allows you to adjust the direction of flow to wherever you would like in your aquarium.
We do recommend the use of some plastic ratchet clamps or other clamping solution to ensure a secure fit on the barbs. Return Jets are available in two sizes for either 1/2" to 3/4" ID hose, or 3/4" to 1" ID flexible hose.
Note: Hose not included. CPR Return Jets use a custom ball and socket connection to allow the flow to be angled anywhere in the tank. This socket is not designed to work with other ball and socket style connectors.

This can be a bit of a complex question because this depends upon a number of factors including input pressue and acceptable pressure loss and velocity. Ultimately for most practical applications and regular hobby pump pressures, the most you are going to get through a 1/2" ID pipe such as the return jet would be about 400-500gph. For a 3/4" line you may get that up to a bit under 700gph. Bottom line, for those returns you are almost definitely being flow limited by the ID and losing flow capacity from your pump.
Hope this helps!
The gap in the "U" of the return jet is just shy of 2 1/4", so anything under this should be fine. The ball joint starts at about 2.5", and the actual outlet starts at about 3.5" from the inside bend. Hope this helps!
This return jet in the 1/2" to 3/4" size will work with your 5/8" tubing. We recommend a zip tie or hose clamp to hold the tubing. Feel free to let us know if you have any further questions!
Unfortunately this would not connect directly to the return jet. You would need additional plumbing fittings in order to do that.
While similar in concept they are not interchangeable. Loc-line is a brand name with its own standard that isn't interchangeable with other similar looking fittings.
