Is anyone familiar with this type of nipple?

The one's from the second site you listed in your post ship from China so they will take an awfully long time to get to you, which also means returns can be quite the hassle getting them back to them if they don't work out. I have bought other items from that site and it has taken between 4-6 weeks for delivery and customer service can be, tricky.

I'm going to go with the ones Hosspak posted.

The only problem with ordering was they listed 2 Day priority mail for the shipping but it took 7 days, this only matters if you're in a rush. I wasn't so it wasn't a big deal. I think you will like them.

I'm in no big hurry, as long as I get it all completed by early spring.
