Brass Water Butt Tank Adapter, 1" BSPM to 3/4" BSPF

Constructed from high-quality brass, this water-butt tank adapter features a 1″ BSP male inlet (33.25 mm) that reduces to a 3/4″ BSP female outlet (26.44 mm) through the entire fitting, allowing connections on either side. It requires a 33 mm installation hole and comes complete with a back nut and washer for a secure, leak-proof seal.

This brass adapter is engineered for rainwater harvesting and fluid-storage systems, providing a robust, corrosion-resistant connection between pipes or fittings of different sizes. The through-thread design lets you attach hoses or connectors to either end without additional parts.

If your container already has a 1″ BSP female thread, simply screw in the male end for an immediate, leak-proof joint. Where no thread exists, drill a 33 mm hole, pass the adapter through the wall, then secure with the supplied washer and back nut. The internal washer ensures a watertight seal, while the nut locks the fitting firmly in place.

Ideal for adapting water-butt setups or other containers, this adapter offers flexibility and long-term reliability in outdoor environments. Its brass construction resists UV exposure and environmental wear, ensuring consistent performance over time.
