Why Choose Our High Flow Drain?

• Massive 50mm Flow Rate: Specifically designed for large-volume water management, preventing pump overflow and ensuring rapid, efficient drainage during routine tank maintenance and water changes.
• Thick Wall Compatibility: Features an extended 35mm thread length on the main body, allowing it to securely clamp onto heavy-duty glass, acrylic, or fiberglass tank walls up to 15mm thick without compromising structural integrity.
• Integrated 1.5" Female Thread & Plug: The internal 1.5-inch (46mm diameter) female thread offers incredible versatility. You can easily screw in the included blue plug to seal the drain, or attach other 1.5" threaded filtration components like strainers and standpipes.

⚠️ Crucial Installation Guide: This bulkhead requires a precise 60mm hole cutout in your tank wall. The bottom slip end connects directly to standard 50mm Outer Diameter (OD) rigid pipes. Always ensure the silicone sealing gaskets are placed correctly on the wet side (inside) of the tank before tightening the external locking nut to guarantee a 100% leak-proof seal.
