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
- All batches are tested, the manufacture use FDA approved silicone and have them independently tested in Hong Kong
