Does anyone know what the orifice"3.0, 4.0, 5.0, 6.0, 7.0" (and so on) mean?! Regarding orifice sizes and pressure washer pump sizes, (like a chart)?

Don't know about a chart but the sizes represent the width usually of the spray. The narrower the spray coming from the nozzle, the more pressure you have. The pressure washer pump runs the same regardless of the tip size so a 2500 psi washer may produce only 1500 lbs pressure with a 12" wide spray.
1486215
There are charts with price sizes versus PSI pressure. You need to know your pressure washer's output then look on a chart for the correct size.

The Orifice # like 3,4,5, Etc would be the # gallons per minute at the standard pressure of 4000 psi. The ratio is not linear. A #4 would pass 2 gpm @ 1000 psi, 4 gpm @ 4000 psi and 5.7 @ 8000 psi. An excellent chart at "ultimatewasher.com".

This is actually a 3/8" quick-connect. Consumer-grade pressure washers (such like you'd find at HD or Lowe's) are sized as a 1/4" quick-connect (like the spray-tip of this unit is). If you've got a similar setup (most consumer-grade units are similar), you'll want to get a male M22 to 3/8 quick-connect to hook up to your pressure washer hose so that you can use this wand.You may need to get a couple different adapters - Amazon has the Forney 75117 (Male M22 to 3/8" Male NPT) and the Forney 75129 (Female 3/8 NPT to Female 3/8 Quick-Connect) which should do the job.

Hi Maureen, this washer is a great machine and has 4 different ez to change nozzles that will allow you to interchange for different pressures that are required for various jobs. Wouldn't hesitate for the price, am more than happy with mine. Take Care...Lee

I measured the O.D. of the largest part of the barb with my caliper and it showed .305". The largest part of the fitting up against the nut, is .313". Mine came with a piece of tubing about 7" long to connect to the a 6 valve outlet port (included). The barbs on the oulet ports measured .205". I've had this air pump for 2 years now running non-stop with zero defects. If all the ports are used the pump is fairly quiet for its size and it really moves some air. When used with airstones the water looks like it boiling. It tends to run a little hot but this hasn't seemed to affect the pumps performance. This pump is little animal. I think it would air up a truck tire. I'd buy it again in a second. Hope this helps. I measured the O.D. of the largest part of the barb with my caliper and it showed .305".

The majority of the pressure washer tips I've found all fit my washer with no problems, but your PW is 3100 PSI, and this is rated for up to 3000 PSI. It would work, but with the extra pressure it would probably just wear out a little bit faster than my 2700 PSI washer.

According to the chart, you need either a 4.0 or a 4.5 nozzle, NOT this one. Here is a link to a chart: http://www.pressurewashersdirect.com/Shark-9.302-243.0/p4389.html#reviews Here is another chart, less commercial: http://www.the-power-washer-advisor.com/pressure_washer_nozzles.html#NozzleChart

It fits both of my pressure washers. 1 is a harbor freight 1500 psi, sorry the model number is gone. It also fits my 2500 psi gas Troy Bilt, not sure if I'm lucky but I think the hoses are pretty much universal

Hi Richard, This works on all pressure washers to be honest. I used this on my honda gas pressure washer and my electrical one. The fit on the extension is standard fit on most hoses I hope this helps

It's the bubble measurement. However, I found that the flange was a bit smaller than the original one I replaced.

I know from trying to spec my PW pump that there is a plethora of pump and housing designs. The best way to make sure something fits is to get the model number from the pressure washer (there should be a data plate near the engine base). Search Google or amazon using the model number and the word "pump". This particular pump is used on a Husky pressure washers with a Honda engine.

I have this same washer and pump. It did in fact fit and work excellently.Note that the outlet of the pump was oriented opposite than the setup of 131889800, but both pump shrouds can be re-oriented.In the washer in question this pump's default orientation was an improvement as outlet drain hose was could be routed with less obstruction. Worked excellently.

It's rated for washers up to 3300psi. If you have a 3.8 hose, then it sounds like you have a 4000psi washer.

I had a 3100 psi at 2.5 gallons per minute, and this attachment worked great, and the quarter inch quick connect it will fit which most pressure washers under 4000 psi are, so go for it it works great I haven't had to use any tips since I got this attachment,

Hi. I have absolutely no idea what that means. I would hazard a guess that if you are looking for Interpupillary specifications, then this is the wrong model for you.
