For turbo nozzle you have the comment: Will not fit Simpson or Generac spray wands Do you mean the gun because it has a M22 connection or it won't fit the was with quick release at the end. Thanks,
Eric

Answer
No, that is a mistake on our website. This unit will fit those models. The issue is the Generac and Simpson quick connect couplers are to shallow to accept the standard 1/4" quick connect plugs. However, the plug being used with this will fit those units.

Hello Bill, I have a honda gx340 11hp petrol motor couple to a nilfisk/gerni pump 35l/min at 250bar (9.23Gal/m 3600psi) Can you suggest a turbo nozzle for this unit..?
Mal

Answer
You would need a 10.0 size nozzle. I am posting a link below to the nozzle we carry on our site in this size:

10.0 Shark Turbo Nozzle

Is a 4.0 orifice on a General Pump turbo nozzle correct for a Simpson PS4240H-SP pressure washer? Does the Simpson PS4240H-SP come with a 1/4" quick connect on the lance?
Rod 
from California 
October 08, 2011
Answer
Yes, the 4.0 size orifice is the correct size for that pressure washer. In regards to the lance, yes it comes with a standard 1/4" quick connect connection on the end of the lance.

How do I find out what GPM my machine is? What is GPM?
Jeffrey Helwig 
from New Hampshire 
August 04, 2011
Answer
The gpm is the max gallons per minute that the pump is capable of putting out. This rating should be listed on the pump and/or frame of the pressure washer.
