  • Great hose for home use.
Size: 50-Foot (5/16 in Diameter) Style: 3700 PSI
I bought this to replace the factory hose that came with my 3400 PSI Ryobi Pressure Washer (Auto-Idle version). The factory hose ended up leaking, even after multiple attempts to fix the leaks. The leaks were so bad, that the pressure washer wasn't able to idle, not to mention the length of the hose was too short for me to wash my cars. This hose, however, is awesome. Very durable, does not leave marks on the ground, does not leak, easy to use, and it is very long. I can practically put my pressure washer at the end of the driveway, and wash all the cars in it without having to move the unit. It doesn't leak, and what I found most interesting in their hose ends, vs. the Ryobi factory one, is that the Simpson has 2 O-rings per end, and the connections actually screw on deeper than the factory Ryobi hose. Pretty much, if it leaks, it will be because this hose is very very old or the o-rings go bad. Because of the attempts to reduce the leaks, the Ryobi pressure washer can deal out quite a bit of water now, and it can idle like it is supposed to without issues. The only downside vs. the Ryobi factory hose is the thickness of the hose. Granted, the diameter of the Ryobi hose was about the size of my pinky, but with this hose, you will have to unwind it every once in a while when using it. However, it does not kink, and that is a good thing. However, all of this is expected for a hose built with this kind of heavy duty quality. It did come with extension adapters, but I have not used them. I threw my old hose out due to the leaks it had, and currently I don't need to add any more hose. ... show more

  • Oem replacement BUUUT...
Size: 50-Foot (5/16 in Diameter) Style: 3700 PSI
OMG. This hose is stiff. Stiff. If I leave it laying in the sun in July at a 100°. Then I can roll it up. Someone else mentioned this but I always buy OM replacement parts and this time it bit me. I thought my old one was stiff because it was old. It did last like ten years eventually burst. So nice hoes very stiff would not buy again... ... show more

Pretty good pressure washing hose so far. It looks high quality to me. I didn't use it for a long time so I partly review it based on the brand reputation which is ine of the best.
