This 15mm Compression Fit Tank Connector Lug is engineered to provide a secure, watertight pass-through connection for a 15mm copper pipe through the wall of a water storage tank, cistern, or cylinder.
Manufactured from high-grade brass, it features a 15mm mechanical compression connection (nut and brass olive) on one end, a threaded barrel with an integrated anti-rotation lug on the body, a heavy-duty back nut, and an internal rubber sealing washer. The unique lug feature prevents the fitting from spinning when tightening the back nut against the tank wall. Ideal for cold water storage tanks, feed and expansion cisterns, and secondary water setups, it provides a robust, mechanical, and re-serviceable tank entry point without requiring soldering.
