Can I get any kind of spray pattern that I want?

Yes! Since we are drilling each nozzle to order, customer requests for a special or non-standard pattern can be accommodated without a problem. We do reserve the right to charge more for especially difficult or complex patterns.

I have an old jetter, or the manufacturer is out of business, can you supply nozzles for my equipment?

Not a problem. As long as you know the pump’s flow and pressure specifications we can set up a nozzle that will work great on your equipment. We will also need to know the thread size. If you’re not sure about that, refer to the thread selection chart at the bottom of the page by clicking HERE!


If the nozzles are custom drilled, does that mean I have to wait long to get them?

Surprisingly not. We stock our nozzle bodies in an undrilled condition and have a very efficient system for drilling. We are located in the Richfield OH (Eastern time zone), and most orders that are placed by noon local time will ship that day. Occasionally, we will have to ship on the next business day.

I'm not sure about the thread size; how can I check?

The hose diameter cannot be used as an indicator of the thread size on the

hose connector fitting. If you are not certain, click HERE and scroll down to find the thread measurement table at the bottom of the page. Measure the outside diameter (O.D.) of the fitting's thread then round to the closest reference measurement and note the corresponding NPT size.

How are the nozzles priced?

We are a manufacturer, and you save by buying direct. Prices are listed on each product detail page and include drilling with the pattern of your choice. We offer quantity discounts which start with six nozzles. We also welcome inquiries from distributors or resellers, and have a special discount plan for those who qualify. Please call us toll free for details.

When choosing a pressure washer or jetting equipment, PSI and GPM are both equally important. The PSI refers to the amount of "stripping" power produced to blast off grime with force and the GPM refers to the amount of water needed to move/rinse the dirt and grime out of the drain.

Another important factor that's equally as important but not often considered, is the Cleaning Unit (CU) the equipment will generate. A Cleaning Unit is the result of multiplying the PSI by the GPM. Cleaning Units gives us a measurement of machine performance (efficiency) when comparing one piece of equipment to another.

Examples of Cleaning Units (CU):

Unit A has 3000 PSI and 2.0 GPM = 6000 Cleaning Units.
Unit B has 2000 PSI and 3.0 GPM = 6000 Cleaning Units.


What's the Difference?

The rinsing power is greater than the stripping power in unit B meaning that unit B will clean (move/rinse dirt away) faster than unit A. Although the CU is the same in both units, the higher the GPM, the faster the job will be finished.

While water pressure provides the power to break up dirt and grime, water volume is what flushes that broken filth away. Essentially, the more water that moves through a nozzle per minute, the faster you'll be able to clean!



GPM (Gallons per minute) - The amount of water that is coming from the machine.


PSI (Pounds per Square Inch) - The amount of cleaning pressure that a machine can produce.

NPT (National Pipe Thread) - National technical standards for screw threads used on threaded pipes and fittings. They include both tapered and straight series for various purposes including rigidity, pressure tight sealing, or both.
