1/4" RODI Tubing U-Bend Guide / Hanger for Reef Tanks

I designed this simple yet essential tool specifically for reef aquarium hobbyists.

This is a U-shape bend guide (flow bend clip) designed to hold standard 1/4-inch (6mm) RODI tubing in a smooth 180-degree curve.

Why I made this: Standard 1/4" RODI tubing is notoriously stiff and prone to kinking or crimping when you try to bend it sharply over the rim of a tank or container. This restricts water flow and can be frustrating to manage.

This guide allows you to neatly hang the tubing over the edge of your aquarium, sump, or water reservoir without kinking the line.

Perfect applications for reef tanks:

Hanging the output line of your RODI water filter into a collection bucket orATO reservoir.

Securing the refill tube for an Auto Top Off (ATO) system over the sump rim.

Organizing tubing for dosing containers.

Just insert your 1/4" tubing into the channel, and it will hold the perfect U-shape curve securely.
