Chicken Watering Nipple ADAPTER to PET soda bottle

I made this adapter (JUST THE GRAY PART IN THE PICTURES) for a buddy who raises chickens on a small scale. He is using the red poultry nipples and sticks them in to soft drink bottle caps but they leak. I designed an adapter that is threaded and does not leak.

I used the "necks and caps" thread for my my soft drink side of the adapter and my own thread design for the poultry nipple side.
