ALTO Speed 4050 X-TRA domestic pressure washer high pressure hose. Rated at a maximum pressure of 160 Bar or 2320 PSI
M21 screwed fitting onto the pressure washer, and 3/8 fitting onto the gun or pistol grip. So there's a good chance it will suit the early Gerni's that don't use the quick release hose fitting to the pistol grip or gun.
