Carolina Aqua Nipples don't exist anymore?

[R20]

In lieu of the Carolina Aqua Horizontal Watering Nipples sold by Heritage Market, has anyone had any luck with using the similar types produced out of China? I've heard they're not the same. All sources for the Carolina Aqua nipple are out and have been for months.
