Jubilee clip size 2A (2A (35 to 50 mm OD))
Where 2A (35 to 50 mm OD) is used, its real dimensions, and how to connect it.
Used on: clamping larger 32 to 40 mm pond and pump hose over a hosetail in the 35 to 50 mm band.
A Jubilee size 2A covers 35 to 50 mm outside diameter, which suits the larger 32 and 40 mm pond hoses once they are stretched over a hosetail. Match the clip to the outside diameter on the spigot, not the nominal hose bore, which is always smaller.
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.
