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.

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

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.

Power Equipment Direct Recommended

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.

Dissatisfied With Nozzle
Purchased turbo nozzle and was very impressed with how it was working. Worked what I thought was great for 5 houses. Then it stopped spinning i assume hard water deposits. I soaked it with wd40 several times. No luck.

Purchased another one and on the first day my employee didn't click the nozzle fully in and it flew out when we activated it. The second nozzle stopped working when it hit the ground. Now I have 2 nozzles that don't work.

Now I had the opportunity to check the houses I... more

Michael,
Turbo nozzles are very good at removing dirt & stains from nooks and crannies in durable surfaces like concrete and pavers since they produce a powerful, focused spray. They are usually too strong for softer surfaces like brick and vinyl.

They also work well blasting seaweed off metal pontoons, and getting crud off farm machinery- these are all fairly close up situations.

They really aren't the best at surfaces far away, unless you're after a specific area and then follow up with the regular nozzles- different tools for different purposes.

Turbo nozzles should always be started with the wand facing downward- this prevents the spinning disc inside from getting jammed. I know you didn't mean to shoot it into the ground but turbo nozzles, especially the ones with ceramic inserts, can be damaged by rough treatment.

You may want to check our How-To Library for tips on how to get the best results in various cleaning situations.

Well Worth It
I've always wanted a turbo nozzle for the pressure washer I purchased from you two years ago. And finally broke down and bought one, and couldn't be happier.

The son of a gun works well for concrete, decks and vehicles ( adjust pressure of course). Another tool well worth having.

Michael,
I will make sure our warehouse manager sees your comment; since you're in the business you know wrapping and boxing the nozzle will add to the cost.

Turbo Nozzle Is The Man!
I bought the General Pump Turbo Nozzle to go with my new pressure washer and it is awesome.

A must-have accessory, especially for concrete pressure washing like sidewalks, driveways, garage floors, patios, etc. It makes pressure washing these items a breeze.

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.
Pros: I'd Buy It Again, Fast, High Quality
Cons: Durability

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.

Sale Pricing Is Not Lying
I tried to buy the Turbo Spray nozzle for the advertise price of $69.99 for the 3.5 orifice size but was on the 4.0 orifice page. When I went to the 3.5 orifice size page, the price was $79.99.

So, I called the company and explained that I could not find the 3.5 orifice size for $69.99. I explained that the 4.0 orifice was listed for $69.99 and they said, well its more money for a bigger size. I said that it is not a bigger size. Its actually smaller. when they finally understood what I... more

Robert,
The price for the 3.5 AR Pro Turbo nozzle is $79.99. The price for the General Pump 4.0 Pro Turbo nozzle is on sale for $69.99, thanks to an arrangement with the folks at General Pump.

Our arrangement with General Pump will not affect the pricing for AR products, they are different brands.

It's like apples and oranges; different brands can have different pricing. Nozzle pricing within the same brand will usually change by the grade, since a better grade uses heavier duty, more expensive components.

We're sorry we couldn't explain this to you in a way you could understand. You may want to check "How To Pick The Perfect Rotary Turbo Nozzle" in our How-To Library for more information.
