Constructed from high-quality brass, this water-butt tank adapter features a 3/4″ BSP male inlet (26.44 mm) that reduces to a 1/2″ BSP female outlet (21 mm) through the entire fitting, allowing connections on either side. It requires a 26 mm installation hole and comes complete with a back nut and washer for a secure, leak-proof seal.
This brass water-butt tank adapter reduces from a 3/4″ BSP male thread to a 1/2″ BSP female thread, with the internal thread running the full length of the fitting for connection on either side. The robust brass construction resists corrosion and UV exposure, ensuring reliable performance in rainwater harvesting and other fluid-storage systems.
If your container already has a matching female thread, simply screw the male end of the adapter into place for an immediate, leak-proof joint. Where no thread exists, drill a 26 mm hole, position the adapter through the wall, then secure with the supplied washer and back nut. The internal washer provides an effective seal against leaks, while the external nut locks the fitting firmly in position.
Ideal for adapting pipework or fittings of different sizes, this adapter offers flexibility and durability for any water-butt or container setup. Its through-thread design allows you to attach hoses or connectors to either end without additional fittings.
