The threads on this connector are machined so precisely that it screwed on with zero wobble. It’s clearly a genuine replacement part, and the dual male threads fit both my 3/8 and 1/4 lines without any adapters. Solid build, no leaks.
The threads on this connector are machined cleanly, so it screwed onto my hose without any cross-threading or leaks. I’ve used it to connect my pressure washer, and the fit is snug and reliable even at higher pressure.
Finally got my Rocket machine running again after swapping in this connector—the threads are precise and it sealed perfectly on the first try. Only took about 10 minutes to install, though I wish the brass finish matched my machine's trim a bit better.
