⚠️ Sizing & Installation Guide (Crucial!)

Please note that this is a fully threaded fitting. Read the Atradesen.com installation rules carefully to avoid leaks:

• 🚨 TEFLON TAPE REQUIRED: You MUST wrap the male threads tightly with Teflon/PTFE plumber's tape before screwing the plug into a female port. Do NOT use PVC cement/glue on these external threads!
• Imperial Size Conversion: The sizes refer to standard Imperial Male Pipe Threads (MPT). 20mm matches a 1/2" Male Thread, 25mm matches a 3/4" Male Thread, and 32mm matches a 1" Male Thread.
