Q: HI Mike,

We have a Excell 2600 PSI Max-XR2625 powered by Honda. It is a quick connect 5/16 in hose. We are looking to get a longer hose than the 25ft one we have. Will the Karcher 50ft QC and M22 work with our pressure washer?

by Lisa from Oregon on August 18, 2014

A: Yes, this is a rubber hose and one of the best hoses available that is 5/16" in diameter. It comes with all the necessary adapters to connect it to your unit. I would not hesitate to recommend this item.

Q: Hi Mike,
I have a Generac 3100 psi pressure washer and am looking for a longer hose. Will th Karcher 50 ft Model 9.558-124.0 work okay with my unit and will I notice much drop in pressure going from a 1/4 to 5/16 hose? Thanks

by Jim Muirhead from Washington on June 05, 2014

A: Generac uses M22 connectors, so this hose should be fine for you. With a 3100 PSI unit the pressure drop from going to a slightly large hose won't be noticeable, especially if you're going to use the 50 foot instead of the 25 or 30 foot hose that came with your pressure washer.

If you're going to use the 50 foot AND the 25 foot hose together, you may see a slight difference, but it shouldn't affect your pressure washer's performance much. The rule of thumb is that you can double the length of your original hose without a decrease in performance, but if you go past that you will start seeing a drop in pressure.

Home Owner
The quality of the 50 foot hose is excellent. The reason for the less than perfect rating is related to the fittings supplied with the hose. If there were another female quick coupler supplied with the kit, the hose would be quickly coupled to the pump and to the wand.

The supplied fittings allow for quick-coupling to one end of the hose, not sure what purpose the second supplied male nipple has.

Good Product, As Expected
I used this so I could be up on a lift leaving the pressure washing unit on the ground. The hose seems to be well constructed, no leaks around the fittings.

Only thing I would note is this is a relatively rigid hose, so while it sometimes needs to be uncoiled and spun around a little to get the loops out for the extra distance, the converse side is it may be more durable. Only time will tell.

No Surprises
The replacement hose for my pressure washer was exactly as described. I received it within a couple days, no hassle no complaints, I would shop here again and would recommend PED.

It Is A 5/16" Hose
The hose quality seems fine. The issue for me is that it's a 5/16" hose, not a 3/8" hose. The specifications state that it's 3/8" but the only thing that is 3/8" is the QC. Hose is 5/16".

We are sorry for the confusion! We've updated our page and specify the 3/8" quick connector, the M22 connector, and the 5/16" hose separately- hopefully that will help future customers.

We've also put a note on your file that if you'd like to return the hose we will be happy to waive the restock fee. Please call us for a Return Authorization as described on our Return Policy page.
