Standard PVC Flush Mount Aquarium Drain Bulkhead (20-75mm) | Flat Head Bottom Connector | Single-Side Pipe Slip

Standard Flush Mount Aquarium Drain Bulkhead

Achieve a perfectly clean fish tank with our Standard Flat Head Drain Connector from Atradesen.com. Designed specifically for bottom drainage in standard glass aquariums, this bulkhead sits completely flush against the tank floor, ensuring 100% thorough water removal with zero dead zones.

🌟 Key Features & Important Limitations

• Zero-Residue Flat Head: The interior flat profile allows all detritus and water to drain completely without obstruction.
• Standard Thread Design: Cost-effective profile optimized for standard commercial aquariums (clamps standard glass thicknesses).
• 🚨 Single-Sided Pipe Connection (PLEASE READ): The flat head inside the tank CANNOT connect to a pipe. PVC pipes can ONLY be glued into the protruding socket on the outside/bottom of the tank.
