Glass U-Tubes

Introduction

Glass U-Tubes (10mm & 20mm) are clear, durable aquarium accessories designed to route airline tubing (6mm / 1⁄4) smoothly over the tank rim without bending or kinking. They help maintain proper airflow while giving your aquarium a clean, professional appearance. The 10mm model is ideal for rimless or thin-rimmed tanks, while the 20mm model fits thicker, standard-rimmed aquariums. Both options reduce visible, twisted tubing and improve overall aquascape aesthetics.
