🌟 High Visibility & Aquarium Safe

• Crystal Clear Monitoring: The high-transparency material provides a direct window into your fluid dynamics, ensuring your filtration system is running flawlessly without any hidden debris buildup.
• 100% Non-Toxic: Manufactured from premium drinking-water-grade UPVC. Completely safe for sensitive marine reef tanks, freshwater shrimp, and potable water.
• Seamless Extension: Perfectly joins two sections of clear PVC pipe in a straight line with zero flow restriction. Ideal for reconnecting pipes that had to be cut during installation.

⚠️ Sizing & Connection Guide (Crucial!)

Avoid ordering the wrong size! Please read the Atradesen.com connection rules carefully:

• 🚨 SIZING LOGIC (Inner Dia. matches Outer Dia.): The sizes listed in the dropdown menu (e.g., 25mm) refer to the Inner Diameter (I.D.) of the two socket ends on the fitting.
• How It Works: These sockets are designed to sleeve OVER your rigid PVC pipes. Therefore, a 25mm I.D. coupling perfectly connects two clear PVC pipes that each have a 25mm Outer Diameter (O.D.).
• Installation: PVC waterproof adhesive/glue MUST be used on both slip joints to secure your pipes permanently (glue not included).
