Water Butt Adapter & 13mm Irrigation Valve

Choose between 1/2″ BSP or 3/4″ BSP sizes in either a standard or extended (+4 cm) length with this robust adapter, moulded from high-quality, corrosion- and UV-resistant plastic. Deep-cut threads grip securely into thick tank walls, and the supplied nut and dual washers lock the fitting in place for a reliable, leak-proof seal.

Each kit includes a durable plastic lever valve featuring a fixed 12.7 mm (1/2″) barbed hosetail for direct push-on hose attachment—no extra fittings or tools required. The valve body resists rust, corrosion, UV damage and freezing, making installation and operation completely tool-free and maintenance-free. Mount onto existing BSP threads or drill a new outlet using the fasteners provided for a truly versatile setup.
