21" Supreme / 23" Ultimate ~ Main Gasket larger outside silicone gasket

This is the 7mm larger of the two Capitol D food-grade hollow silicone gaskets. It sits below the original gasket's lower flat part of the interlocking lip.  

We have them custom extruded out of a special high-tech, high-temp resistant food grade silicone.

This is a relatively new addition to the gasket that is installed on the 45º part of the lip.  Use black Permatex Auto silicone gasket maker to attach, installation instructions in the private KK forum owner's maintenance area.

 

The UPS delivery on this should be $14-15,  if it comes back as $30 please write us and will help out
