Looks like the round ends were formed by a little china man with a ball peen hammer. But it works great.
Garbage, they saved 2 cents by using plastic
These valves look good, but the fill valve has a cheap plastic wheel (round red wheel on schraeder connection) strips constanty, I can’t find a replacement for this valve, now gone through third one, all because they switched to this piece of cheap plastic. The last two never made it through first fill, broke when I tried to open before even filling tank!
