🌟 Professional Plumbing & Aesthetics
-
Seamless Extension: Perfectly joins two sections of PVC pipe in a straight line with zero flow restriction or internal turbulence. Ideal for reconnecting pipes that had to be cut during installation.
-
Vibrant Blue Finish: Matches perfectly with our Lesso blue UPVC pipes! Widely used by pro aquascapers to color-code "Return Water" lines, giving your under-cabinet plumbing a meticulous, high-end look.
-
Safe & Permanent Seal: Made from non-toxic, drinking-water-grade UPVC. Creates an impenetrable, leak-proof cold-weld joint when used with standard PVC adhesive cement.
⚠️ 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).
