Some product history and notes:

• The reason silicone was chosen as the material is purely from a cleanliness point of view, the gaskets are neutral and do not have any smell or taste  
• They do not bake hard so removal is easier
• No need to crank the portafilter tight in the machine as you would a hard EPDM rubber (the industry standard) gasket
• Always use a silicone lubricant such as food safe white grease. Silicone does not like petroleum based grease 
• When installing do not use a sharp screwdriver to push them in, the silicone will break. Use the portafilter with the basket removed to install
