The O-ring cherry seal is molded from various materials including FKM-70 (4 types D / fluororubber) and is available in a wide range of 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 defined it as FKM-70, it was referred to as Type 4D (old JIS standard = JIS B2401:2005). Sakura Seal Co., Ltd. offers a wide variety of O-rings, ranging from very small O-rings to large diameter rings, in addition to the general standard sizes specified by JIS standards, and we support 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.
