Universal Second Story Nozzle Kit for Gas and Electric Pressure Washers

I’d like to edit my answer. I found another source that says these are for 2 to 3.5 gpm machines.

They are rated for 3.5 gpm max. You could damage the machine if your gpm is higher. The max pressure for these is 4K so that is other problem you could have.

Both pink and blue nozzles are 0° Spray pattern. This means it sprays water in a stream (straight line) instead of a fan (sprays in the shape of a V). The pink nozzle has a more narrow stream. So it will have more pressure, but will mist at a shorter distance than the blue nozzle. The blue nozzle will have a little less pressure, but will deliver more water at a slightly wider stream. I run these nozzles on a 3000 psi 2.7gal per minute pressure washer. (But have used them on a 3600psi 8gal per minute commercial pressure washer as well)

Hi John! Thanks for your question. The Karcher Universal Second Story Nozzle Kit works with both gas and electric pressure washers rated at up to 4000 PSI. The GPM will vary depending on the PSI of the machine you are using it with. I hope this helps, Karl from Customer Care

Should work, but may not be perfect. The K1710 machine they list is 1700psi and 1.2gpm. I saw the specs for these at another site listed as between 2 and 3.5 gpm.

Yes it will, but it will be a narrow stream and I found that it is useful in doing interior corners and gutter edge work, but not good if you are trying to clean a wide vertical wall. I usually use these nozzles on my 3000psi 3gpm machine, but have had success with a 3600psi 8gpm unit (the blue nozzle can work on 3rd floor, but starts to mist past that)

Hello from Karcher and thank you for your question. The red nozzle is 0 degrees and the blue nozzle is 2 degrees. Kind regards, Karl from the Customer Care Team.
