Tank Bulkhead 2″

DN50 2″ Tank Bulkhead Fitting

DN50 (2″) Tank Bulkhead Fitting – Highest-Volume, Leak-Proof Port Connector for Industrial Tanks

The DN50 (2″) Tank Bulkhead Fitting is a massive, heavy-duty component designed for the most demanding fluid management systems where maximum flow capacity is critical. This robust connector is engineered to be fitted securely through the wall of any large storage container, creating a reliable, watertight, threaded port with a substantial 2-inch diameter.

Constructed from high-strength, corrosion-resistant plastic, the fitting guarantees long-term durability in industrial, agricultural, and commercial water or chemical storage. Its multi-piece compression design utilizes large hexagonal nuts to powerfully clamp the tank wall, guaranteeing a potent, leak-proof seal against hydrostatic pressure. The large internal threading is compatible with standard 2-inch pipe fittings, enabling the attachment of large pumps, high-flow drain valves, or large-scale filtration equipment.

Key Benefits

• Maximum Flow Capacity: 2″ diameter is the largest standard size, ideal for maximum speed filling, drainage, and circulation.
• Watertight Seal: Compression design ensures a professional, high-pressure, leak-proof connection through thick tank walls.
• Corrosion Proof: Durable plastic construction is completely immune to rust, making it perfect for long-term liquid storage.
• Easy Installation: Large hexagonal nuts and body allow for high-torque, tool-assisted installation and secure tightening.
• Industrial Grade: Built for heavy-duty use in commercial and large-scale agricultural applications.

Technical Specifications

• Part Number: (Specific to the DN50 model)
• Nominal Diameter: DN50 (Approx. 2 Inch)
• Material: High-Strength, Corrosion-Resistant Plastic (e.g., PVC or PE)
• Connection Type: Threaded Female Port
• Feature: Bulkhead/Tank Connector, Hexagonal Nuts
• Grade: Industrial/Commercial/Heavy-Duty Agricultural

Perfect For

• Creating the main outlet/drain ports on commercial or industrial water storage tanks.
• Connecting high-volume sump pumps or circulation systems to reservoirs.
• Large-scale agricultural irrigation and fertigation systems.
• Any massive container modification requiring a secure, highest-volume liquid transfer port.

Application Instructions

• Hole Preparation: Drill a precise hole in the tank wall sized correctly for the fitting body (requires a very large hole saw or specialized tool).
• Insert Body: Insert the threaded body of the fitting through the hole from the inside (ensure any sealing gasket is correctly positioned).
• Secure Nut: Thread the large hexagonal nut onto the exposed threads on the outside of the tank wall.
• Tighten: Use a wrench or specialty tool to tighten the nut firmly, creating a watertight compression seal. Due to the size, high torque will be needed, but be careful not to crush the tank wall.
• Final Connection: Attach the desired 2-inch pipe fitting, valve, or component to the threaded port.

Pro Tips

• For tanks, always back up the wall thickness around the hole if the material is thin, to prevent crushing when tightening this large fitting.
• Use a sealant tape (PTFE) or pipe compound on the external threads before connecting pipe fittings to guarantee a final watertight seal.
• Ensure the location chosen for installation is flat and provides easy access for connecting heavy 2-inch piping.
• Always check the fitting and the tank wall for stress or cracking after final tightening.
• Due to the high flow, install a heavy-duty 2-inch valve for control.
