"I am exited to release these new nipples. I discovered that the harder rubber was causing some spitting issues. I decided to use a slightly softer rubber to help combat the spitting issues some folks have. I designed them to hold up to the aggressive nature of hard hitting machines such as my Sidewinder.
Made from the most durable rubber I could find. They are just hard enough.
I now modified the outside profile for a little bit of a radius at the shoulder. This will help keep it strong where it needs it most. (Similar time how the old black nipples were).
They have a tapered inside diameter, so as it is pressed onto the post the nipple spreads itself around the needle loop for a secure fit. My favorite part of this style of secure fit is that the nipple isn't stuck to the needle when removing it from the machine. "
