The 1/4" Flexihose enables the operator to get their larger 3/8" hose around tight bends and junctions.
It comes with a quick-connect tail on one end and a 1/4" bsp male thread on the other ready to screw on your nozzle.
Using this short hose means the connection to the nozzle is also shorter so the nozzle can negotiate tighter bends and traps.
Overall length with connecter is 430mm. Without connector 410mm.
