And how?** A: No not really. You might be able to with reducers and clamps but not worth all the trouble. Also that will give you more spots that can fail in the long run. good luck. **Q: Shouldn’t this have a pin hole?** A: Yes! The pin hole prevents back siphon from happening by accident. **Q: Can you remove the ball socket to add spray bar** A: Yes. It should be compatible with most systems. I put an extention and different nozzle on mine and it worked just fine. **Q: Mine doesn't have a hole to stop siphon. Where are and how big is the hole suppose to be?** A: Mine didn't have one either. Where did you drill your's ? I assume on the part that's in the tank, otherwise it would push water out of the hole on the wrong side ## Customer Reviews ### ⭐⭐⭐⭐⭐ NO BUBBLES LIKE SOME OUTFLOWS *by R***T on May 14, 2025* GOOD LITTLE OUTFLOW WORKS GREAT ON MY 75 GALLON ### ⭐⭐⭐⭐⭐ Great option *by J***O on January 5, 2024* Great option to swap the factory outlet option that comes with the Marineland C360 canister filter and any filter that has the same hose dimensions. Allows a more stronger flow which helps cycle the water in my aquarium and helps with surface agitation to help with gas exchange. I would purchase again!!!! ### ⭐⭐⭐⭐ Good product, a little cheaply made. *by S***A on November 1, 2016* Bought this for a 55 gallon. As you can see from the picture it doesn't fit all the way down because the suction cup can't adhere to the glass and trim. If I raise it up on the trim the suction cup fails before I can even get the return pump back on. But the product is as described and works perfectly after 2 weeks. I took off a star for build quality. ## Frequently Bought Together - Multipurpose U Return Pipe U Directional Pipe tube 5/8''~3/4'' Duck Bill Hose - Aqueon Silicone Sealant Clear 3 Ounces - Adjustable Sump Baffle Kit - Refugium Kit for 10 Gallon Tank - Reef Aquarium - Saltwater Aquarium Filter System- Protein Skimmer Sump --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/29672828-multipurpose-u-return-pipe-u-directional-pipe-tube-5-8](https://www.desertcart.be/products/29672828-multipurpose-u-return-pipe-u-directional-pipe-tube-5-8) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-17*
