Well, they got here yesterday and they look good.Can't wait to touch and try them...
...got a shipping notice 3 hrs after ordering,
says it'll be here between 6-21 and 6-28
Nipple thread looks identical and came with excellent instructions.
Extension is nice sturdy plastic and thread-in feels pretty good.
Rubber gasket has a nice balance between firm and soft.
Time will tell how well they install into a cooler, still haven't really looked for one.
