O-ring cherry seal made of 'FKM-90 (fluoro rubber)' material.
The material is made of fluororubber (bivalent type), which excels in heat resistance, chemical resistance, oil resistance, and weather resistance, and also has high hardness, making it capable of withstanding pressure. Before JIS B2401:2012 defined FKM-90, it did not belong to any official standards. Sakura Seal Co., Ltd. offers a wide range of O-rings, from very small O-rings 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.
