Eliminate messy, kinked tubing draped over your aquarium glass with the Stainless Steel U-Bend Connector, available now at www.onyxaqua.com. Whether you are running a high-tech CO2 injection system or simply connecting an air stone, this elegant metal guide ensures your tubing is routed neatly and securely over the rim of your tank without ever restricting airflow or gas pressure.

Designed for both large and small aquariums, this simple but highly effective piece of hardware is a must-have for aquascapers who value a clean, professional aesthetic.

Key Features & Benefits

• Kink-Free Routing: The rigid U-shape design prevents your soft silicone or PVC hoses from folding or collapsing as they bend over the top edge of the aquarium glass, ensuring uninterrupted CO2 or oxygen flow.

• Joint Clamping Teeth Design: Engineered with specialized barbed ends, these clamping teeth securely grip the inner wall of your tubing. This guarantees a tight, leak-proof seal and prevents the tube from accidentally popping off under pressure.

• Premium Stainless Steel: Constructed from high-quality stainless steel, this connector is completely rust-resistant, highly durable, and maintains a sleek, polished look that blends seamlessly with modern rimless aquariums.

• Versatile Application: Universally compatible with standard aquarium tubing. It is the perfect connecting joint for CO2 diffusers, air stones, sponge filters, and aeration systems.

Installation Advice

Quick Installation Tip: Standard CO2 and airline tubing is designed to have a very snug fit to prevent leaks. To make attaching the tubing to the stainless steel connector easier, simply dip the end of your hose into a cup of warm water for 10–15 seconds. This will temporarily soften the material, allowing it to easily slide over the joint clamping teeth for a secure, airtight seal.
