Q: 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,

by Eric from South Carolina on April 25, 2015

A: 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.
by Brian, Product Expert

Q: 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..?


by Mal from Hawaii on March 30, 2012

A: 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
by Brian, Product Expert

Q: 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?
by Rod from California on October 08, 2011

A: 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.
by Brian, Product Expert

Q: How do I find out what GPM my machine is? What is GPM?
by Jeffrey Helwig from New Hampshire on August 04, 2011

A: 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.

It's the next step up from our Better recommendation.

The big daddy of turbo nozzles. We have been selling this one since the beginning and it's a favorite year after year for our customers. The nozzle can handle up to 5100PSI And 212 F

The 4.0 orifice is fairly popular, since you want to maximize all the pressure in your washer.

Regardless, you will have to determine the correct orifice size nozzle to purchase based off of your pressure washer's psi and gpm ratings.

Buy It!!!!!!!!
Buy this!!!!! It save so much time. I used this to clean side walks and driveway that turn black and green. They are bright white now.

Really I can't say enough of how much time it saves and how much better the sidewalks turned out.

Not As Powerful As 0, But Still Has Its Uses
Works well, but definitely not as powerful as the 0. I was hoping that it would be as powerful, as I bought this to remove an incorrectly installed waterproofing membrane on my foundation. Getting the old one off required a massive amount of power. my 0 could do it, but my next size up, 15 did nothing.

This worked for the looser stuff and was definitely much faster, but the hard stuff I still needed my 0.

i also tried this on a small part of my deck just to see how well it worked, and... more

Worth Every Penny!
This nozzle does a fantastic job of cleaning, it is FAST, and does NOT leave the little swirl marks like cheaper nozzles.

I got it to clean a concrete parking pad in front of my garage. My house is in the woods, the concrete was almost black from tree sap and dirt. I had put off cleaning it because last time I did it was an all day project. I was hoping this nozzle would help, and did it ever!

I also got a pivoting wand, and adjusted it so it was pointing almost perfectly straight... more

Excellent Nozzle, Worth The Money
Don't know what makes this work so good, but it does. Use it to wash livestock trailers out and it cleans them very fast and very efficiently!!

With the pressure and volume it does great!!
Pros: I'd Buy It Again, Fast, High Quality

Theresa,
There is a small disk with a tiny offset hole inside the nozzle head. The water pressure makes the disk turn very, very fast. The concentrated, spinning stream of water gets into nooks and crannies, scrubbing durable surfaces.

Please be careful using a turbo nozzle on any painted finishes- if you get too close you can damage the paint. Testing in an inconspicuous area will let you gauge how far away to stand for best results.

3rd Use
On the 3rd time using the nozzle stopped working. Called and they sent me another one with no problems.
Pros: Easy To Use, Price, Light Weight, I'd Buy It Again
Cons: Durability

John,
There's a little disk inside that spins under the pressure, and it can get jammed by a piece of grit from your water supply. If it happens again, you can back-flush the nozzle with water to try and dislodge the jam, or carefully clear it with a thin piece of wire or paperclip.

It helps to regularly check and clear the filter screen where your garden hose attaches to the pressure washer; and try not to lay the wand down where dirt can get into the nozzle.

Do It Right The First Time
Great product to clean gum, grease etc. Never use anything else.

Cut your time by more than 1/2. But make sure you select the correct Orifice size to really make a difference. I had been using a 1/2 size bigger for a year and was impressed, but once I got it dialed in it made all the difference.

Keep a rebuild kit on had though, you'll need it. Great product.

Does A Super Good Job
Got the 4.0 General turbo nozzle today. It arrived on schedule, as has the Dewalt 3800 3.5 GPM washer.

This nozzle does a super good job. It's too early to tell if it will hold up, but if so I will stay with this one.
