O-ring cherry seal made of 'HNBR-70 (hydrogenated nitrile rubber)' material.
Made from hydrogenated nitrile rubber, it possesses excellent physical properties, making it highly resistant to pressure, as well as having heat resistance, oil resistance, and weather resistance. Before JIS B2401:2012 defined HNBR-70, it did not belong to any public standards. Sakura Seal Co., Ltd. offers a wide range of O-rings, from very small O-rings to large diameter rings, in addition to the standard sizes specified by JIS standards, and we support the appropriate selection of O-rings in terms of both material and size. * We also accommodate shapes other than O-rings.
