Dan Kubin Half Hard Nipples

From Dan:

"I am excited to release these new perfect 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 to 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."
