I tried connecting to the hose first, but it does not fit. It should be 1/4 flare, but is not the pitch different? I thought that the screw thread (male side) was well observed, and there was a crushed part at the tip of the mountain. Since it is troublesome to replace it, I scraped the mountain with a file and shaped it and somehow fitted.
There used to be similar experiences with no-brand items, but I did not think that I would have experienced this with Taxco's products (though I thought that inspections should be done properly even if they were made in China).
Recently, the quality has increased even with a Chinese-made no-brand item, and it may not be necessary to be concerned with the name of the manufacturer with this product any longer.
