The cherry blossom seal for O-rings is molded from various materials in a variety of sizes, including the AN6230 standard and others.
This is a size series established for fixing cylindrical surfaces, based on the old JIS standard (JIS WG1517). 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.
Inquire About This Product
basic information
The AN6230 standard is one of the O-ring dimension standards that originated from the former JIS standard (JIS WG1517). It is utilized primarily as O-ring sizes for cylindrical surface fixation in industries such as aviation and hydraulics. Furthermore, all AN6230 standards can be converted to AS568 standards (aerospace standards).
