32 mm pond hosetail (32 mm barb (to 1" or 1-1/4" BSP))
Where 32 mm barb (to 1" or 1-1/4" BSP) is used, its real dimensions, and how to connect it.
Used on: larger pumps and gravity-fed filters that need the higher flow of 32 mm hose.
32 mm hose steps the flow up for larger pumps. A 32 mm hosetail usually carries a 1 or 1 1/4 inch BSP thread. Stepped hosetails let one fitting suit several hose bores by cutting the barb down to the size you need.
Quick-connect click fittings from Hozelock, Gardena and Karcher are proprietary and do not interchange. They all sit on top of a standard thread underneath, so the reliable way to move between brands is to adapt at the threaded tap or hose-end fitting, then use each brand's own connector above it.
