⚠️ Factory Image Typo & Installation Guide (Crucial!)
Please read our Atradesen.com installation rules carefully to avoid connection issues:
-
🚨 FACTORY IMAGE TYPO WARNING (1/4" vs 1/2"): The English text on the manufacturer's photo incorrectly states "1/2 inch". The actual external thread on this valve is a standard 1/4" Male Pipe Thread (MPT) (known as a 2-point thread).
-
Adapter Connection: If you purchase the kit, it includes a 20mm Adapter. One end is a 1/4" Female Thread (which screws onto the valve), and the other end is a 20mm I.D. smooth socket (which sleeves OVER a 20mm O.D. rigid PVC pipe).
-
Sealing Rule: You MUST wrap the 1/4" male threads with Teflon/PTFE tape before screwing it into the adapter. PVC glue must only be used on the smooth 20mm slip socket!
