Contains enough fittings to connect the pressure hose to the machine and to the wand, and to connect the machine to your water supply and the water hose to the faucet.The fittings seem to be of pretty good quality and (at least in my setup) don't leak more than the occasional drip here or there on the (city water supply) hoses. No leakages at all at on the pressure side of things for which I am grateful.My kit included 5 wand tips in the standard sizes of 0, 15, 25, 40 degrees plus one that is very wide and is supposed to be used for applying soap if your machine is capable of doing that. Again, they are of pretty good quality and are working well in my setup.I cannot help but recommend the use of the quick connects because it makes it so much easier to do setup and tear down. Just make sure you order the correct thread size for your machine. This set is M22-14 but some machines/hoses use M22-15 which feels like it will work but really does not and will leak and mess up the threads.The other benefit of the quick connects is that they cut down on the amount of kinking that the hose is liable to do because they allow the hose to swivel if it can.Overall I am very pleased with this purchase and recommend it to my friends with their own pressure washers.
