⚠️ 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 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).
