Glass CO2 U-Bend Connector for Planted Aquariums

Prevent unsightly and restrictive kinks in your airline tubing with the elegant CO2 U-Bend Glass Connector, available now at www.onyxaqua.com. When routing CO2 tubing over the sharp rim of an aquarium, standard silicone or PU tubing often crimps, cutting off the vital carbon dioxide flow to your planted tank. This high-clarity glass U-connector provides a smooth, rigid bridge over the tank's edge, ensuring a consistent and uninterrupted gas flow to your diffuser.

Key Features & Benefits

• Prevents Tube Kinking: The rigid "U" shape guides your CO2 tubing seamlessly over the edge of the aquarium glass, completely eliminating the risk of pinched lines and blocked gas flow.

• High-Clarity Glass: Crafted from premium, crystal-clear glass that blends invisibly into your aquascape, maintaining a clean, professional aesthetic without bulky plastic fittings.

• Secure Tubing Connection: Both ends of the U-bend feature subtly flared tips, providing a snug, secure grip on standard 4/6mm (inner/outer diameter) CO2 tubing to prevent accidental blow-offs under pressure.

• Professional Aquascaping Tool: An essential accessory for high-tech planted aquariums, ensuring your CO2 system runs efficiently while keeping the hardware looking sleek and unobtrusive.

Installation Tip

How to safely attach tubing:

Because the glass U-bend is delicate, never force cold, stiff tubing onto the flared ends. Always dip the ends of your silicone or PU tubing into a cup of hot water for 10-15 seconds. This will temporarily soften the tubing, allowing it to slide smoothly and securely over the glass fittings without risking breakage.
