Oase Flow regulator can connect 2 different sized hoses together.
This is a flow regulator not designed for use as a stop valve only to slow or direct water flow
Each side can fit hose sizes 1"/25 mm, 1.25"/32 mm and 1.5"/38 mm.
Each side can be simply unscrewed without the need to pull off the hose or hose clip.
Before fitting simply cut off the smaller sizes so as not to slow down the flow of water.
