Quality feels nice and it has a good weight to it. No leaks so far. Review: No Leaks - Easy to Install - I had been trouble connecting the high pressure hose to my pressure washer and the wand, lately. (I think it may be because the hose has aluminum threaded connections.) I was a little skeptical about buying these because I was worried about leaks. I installed them on both ends of the hose, the pressure washer, and the wand, and tried them out today. I could not be more pleased! Now I can connect everything in less than a minute and, best of all, there are zero leaks. I highly recommend these. ## Features - M22-14mm swivel+3/8''QD - Max. Working Pressure: 5,000 PSI - Max.
