Create secure, leak-proof pipe penetrations through filter boxes, quarantine vats, and pond walls with our range of heavy-duty PVC-U tank connectors and bulkhead fittings. Engineered specifically for aquatic installations, tank connectors provide a reliable, watertight pass-through point that allows rigid solvent weld pipework to enter and exit filtration vessels without compromising structural integrity.
Manufactured from tough, fish-safe, and corrosion-proof PVC-U, each tank connector features a precision-threaded barrel, a wide clamping flange, and a durable EPDM rubber sealing washer. When tightened with the heavy-duty compression nut, the fitting forms an airtight, watertight clamp against flat plastic, fibreglass, or polycarbonate surfaces, resisting continuous water pressure and mechanical vibration from circulation pumps. Internal solvent weld sockets allow standard rigid pipe to chemically fuse directly into both ends of the fitting, making it simple to construct inter-bay transfer pipes, gravity filter returns, overflow weirs, and bottom drain flush connections.
Available in standard imperial and metric diameters ranging from 1.5 inch and 2 inch for pump returns and balance pipes up to 3 inch and 4 inch sizes for high-flow gravity filtration lines, explore our complete tank connector collection to find dependable, builder-approved bulkhead fittings engineered for permanent, leak-free performance.
