🌟 Professional Maintenance & Aesthetics
-
Quick-Release Disconnect: The brilliantly designed center threaded nut can be easily unscrewed by hand, separating your plumbing line into two pieces in seconds. Absolutely essential for installing directly above return pumps or UV sterilizers for easy removal and cleaning.
-
Built-In O-Ring Seal: Features a high-quality internal rubber O-ring that compresses as you tighten the center nut, guaranteeing a 100% leak-proof seal without the need for Teflon tape on the union threads.
-
Vibrant Blue Finish: Matches perfectly with our Lesso blue UPVC pipes! Widely used by pro aquascapers to color-code "Return Water" lines for a meticulous, high-end look.
⚠️ 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. union perfectly connects two PVC pipes that each have a 25mm Outer Diameter (O.D.).
-
Installation: PVC waterproof adhesive/glue MUST be used on the two outer slip joints to secure your pipes permanently to the union halves.
