Threaded Water Butt Tank Adapter, 1"

Crafted from UV-stabilised, weather-resistant plastic, this double-ended water-butt adapter features 1" BSP male threads on both ends and includes a back nut and washer for a secure, leak-proof installation. It’s engineered to accept female BSP fittings or taps directly, making it ideal for versatile rainwater harvesting setups.

The precision-cut threads ensure a snug fit to your tank’s BSP thread, while the external washer and nut lock the fitting firmly in place, preventing leaks even under pressure. Simply drill a 33 mm hole (if needed), insert the adapter, slide on the internal washer, then tighten the nut from the outside for an immediate, watertight seal.

Perfect for both new installations and system upgrades, this connector delivers reliable performance in indoor or outdoor environments and provides a quick, tool-free solution for attaching hoses, taps or other BSP-threaded accessories to your water-butt tank.
