    Premium ABS Waterproof Tank Bulkhead Fitting

    Secure your water tanks, rain barrels, and aquariums with our durable ABS waterproof bulkheads from Atradesen.com. Designed with a specialized locking mechanism, these lightweight yet robust fittings guarantee a vibration-proof, watertight seal for both home and commercial water storage systems.

    🚨 CRUCIAL DESIGN FEATURE (PLEASE READ) 🚨

    • Reverse Outer Thread (Left-Hand Thread): The external thread on this bulkhead is intentionally reversed! It is designed EXCLUSIVELY to be used with the included locking nut to secure the fitting to the tank wall. It CANNOT be used to connect to other standard external pipe fittings!
    • Standard Inner Thread: The inside of the fitting features standard female pipe threads (FPT), allowing you to easily and safely connect standard valves, nozzles, or male threaded pipes from the inside of the fitting.

    ⚠️ Sizing & Drilling Guide

    To avoid leaks, carefully match your drill hole size to the exact Outer Diameter (O.D.) of the reverse thread using our Atradesen.com guide:

    • 1/2" Size (I.D 20mm): Drill Hole: 35mm | Max Wall Thickness: 12mm
    • 3/4" Size (I.D 25mm): Drill Hole: 35mm | Max Wall Thickness: 12mm
