Water Butt Tank Adapter, 3/4" BSPM to 1/2" BSPF
Constructed from robust, UV-stabilised plastic, this water-butt adapter features a 3/4" BSP male thread on one end—complete with back nut and external washer—and a 1/2" BSP female insert on the other, equipped with an internal washer to prevent leaks without needing to bottom out the thread.
For barrels already fitted with a 3/4" BSP female thread, simply remove the nut and screw the adapter directly onto your tank for an immediate, watertight connection. If your container lacks a pre-moulded thread, drill a 26 mm hole, remove the external washer and nut, pass the adapter through the wall, then reposition the washer inside the barrel and secure with the nut. The internal and external washers together form a reliable seal against leaks.
Designed for rainwater harvesting and outdoor water-butt systems, this adapter withstands constant water pressure and the elements, offering a durable, long-lasting solution that’s easy to fit for both DIY enthusiasts and professional installers.
