Great medium-duty 4500psi 50 footer. Comes with 3/8 inch QC couplings, male on one end and female on the other. Includes the o-ring, and it is installed on the female coupling. Also has bend guards on each end, as shown in the picture. Note, this is for higher-pressure machines. This will not work out the box for mid- and lower-pressure machines, such as most every electric washer and most every 2500-3400psi gas washer. It is not the products fault if you order the wrong hose/connectors. You should order this if your setup uses 3/8 inch QC couplings, such as you would find in most every machine above 3500 or so psi. Check your machines specs first before ordering. This will not work out the box with 1/4 inch or 5/16 inch hose setups, unless you change the connectors on this or your system. The hose itself is rated 4500psi. My machine can do 4200psi/4.0gpm. Always, always, always, lower the pressure on your machine when testing new hoses. If the hose bursts or a connector comes undone, this can be a very dangerous situation. Start low and check the entire length of the hose. Gradually increase pressure and re-check the hose. Keep raising it until you reach your desired working pressure and re-check the hose. Use it for a short while and re-check the hose. Really, you should be doing this every time you use your machine, and not just when the hose is new. Its smart and safe. The hoses themselves are high-quality, but I would not say pro quality. These hoses are too flexible for day-to-day use and abuse. These are the kind that will easily kink and ruin themselves if you are not careful. Don't get me wrong. I am not calling them cheap. They are good hoses. However, compared to other comparably-priced pro-level hoses I have had in the past, these are not the best. As long as you can keep them from kinking, they should be fine for many years. As for corrosion in the braiding. First of all, make sure to roll up your hoses in such as way as to allow the water to drain out completely. It takes practice, but you can get most of that water out. Also realize that all hoses have this "problem." Its just that you usually cannot see the braid. These are translucent, and that's why now all of a sudden you can see it. If this is really a problem for you, I would recommend you leave the pressure washing thing to the pro's. Really, this is not a problem in itself. Its normal. Bubbling hoses are bad. Rusted braid, eh, not a big deal. I was able to use two of these plus the OEM 50 footer, for a total of 150 feet with my machine no problem. Still had great pressure at the tip. If you need a long reach, just buy more 50 footers. Do not waste your time, effort and money with 100 footers. 50 footers are better in every way except price. Well, price at least in the short term. In the long run, 50 footers are cheaper. Also, 50 footers allow for easily customized setups. If you only need 50, then only use 50. Add more as needed. Also, if one bursts, its not the end of the show if you get my meaning. When a 100 footer bursts, it hurts your feelings. Also, 50 footers are easier to clean up at the end of the day. I did this as a business for many years. Trust me, stay away from the 100 footers.
