The O-ring cherry blossom seal is molded from various materials, including FKM-70 (Type D / fluororubber), and is available in a wide range of O-ring sizes.
The material is made of fluororubber (type 2), which excels in heat resistance, chemical resistance, oil resistance, and weather resistance. Before JIS B2401:2012 designated it as FKM-70, it was referred to as Type D (old JIS standard = JIS B2401:2005). Sakura Seal Co., Ltd. offers a wide range of O-rings, from very small to large diameter rings, not only in general standard sizes according to JIS standards but also supports the appropriate selection of O-rings in terms of both material and size. * Various types of fluororubber are the specialty of Sakura Seal Co., Ltd. * We also accommodate shapes other than O-rings.
