Dosing/Airline Tube Holders - Multiple Styles

Keep your airline and dosing tubing tidy, protected, and exactly where you need it.

Printed in durable PETG, these tube holders route and secure flexible tubing between 3–6mm. They're a great fit for common airline tubing, aeration lines, and reef dosing lines. Instead of tubing tangled across your tank, stand, or dosing station, snap it into a holder and keep everything running clean and organised.

Holders can be attached to glass or cabinet surfaces using double-sided tape or adhesive (not included), so you can mount them exactly where you need them.

Pick the style that matches how your lines need to travel:

• 90º Internal Corner – 4 Lines: Guides four lines around an inward-facing 90° corner. Ideal for tucking tubing neatly into the inside corner of a cabinet, stand, or sump compartment.
• 90º External Corner – 4 Lines: Wraps four lines around an outward-facing 90° corner. Perfect for taking tubing around the outside edge of a tank frame, stand, or equipment housing.
• 90º Elbow – 4 Lines: Turns four lines through a 90° direction change at a single point. Useful anywhere a run needs to bend cleanly without kinking.
• Straight Channel Holder – 4 Lines: Holds four lines running in a straight line, keeping them aligned along flat runs behind the tank, along a stand, or across a cabinet back.
• 20cm Holder (up to 12mm Glass): A 20cm strip that clips straight onto glass up to 12mm thick, letting you run and organise tubing directly into the tank for mid-depth sampling or dosing.

All five styles are made from PETG for long-term durability around water and equipment, and suit flexible tubing 3–6mm, including most common airline and reef dosing tubing.
