The cherry blossom seal for O-rings is molded from various materials in various sizes, including the SS standard and others.
The SS standard, often incorporated into small machines, is a size series composed of the smallest O-rings. Sakura Seal Co., Ltd. supports the appropriate selection of O-rings in terms of both size and material, offering not only general-purpose materials based on JIS standards but also various high-performance materials such as the "Floro Power Series," which features Perfluoroelastomer (FFKM) at its peak, and the "Floro Up Series," characterized by low adhesion, low friction, low sticking, and low outgassing.
