Each Gasket replacement kit includes 3 Base and 3 Cap Replacement Gaskets
The Gasket in the base provides shock absorption protection
The Cap Gasket provides an airtight seal in addition to shock absorption properties
To replace the gaskets in your JyAR:
Step #1: Simply pry each gasket free by using a butter knife (knife with a rounded tip) to lift one edge of the gasket away from the protective cap or sleeve.
Step #2: Gently lift the gasket up and slowly remove it.
Step #3: Insert the new Cap or Sleeve gasket and "seat it" with your fingers.
