This item enables you to connect a water butt/rain barrel or water storage tank to a garden hose. The threaded adapter features a 3/4" BSP thread, requiring a 26mm hole or an existing 3/4" BSP female thread for installation. Simply remove the nut and washer, push the adapter through the prepared hole, then replace and tighten the washer and nut. The universal garden hose connector can then be screwed onto the threaded adapter, making it ready for use. Both parts are made from high-quality materials, ensuring precise molding for a leak-free, secure hose connection.
