Standard type Afuras made of O-ring cherry seal (FEPM) material.
The material is made of Aflas (FEPM), which has excellent chemical resistance and is also resistant to strong acids, strong alkalis, and steam. Additionally, it surpasses Perfluoro (FFKM) in amine resistance and possesses rare properties such as radiation resistance. Sakura Seal Co., Ltd. offers a wide variety of O-rings, ranging from very small O-rings to large diameter rings, in both general standard sizes according to JIS standards and various sizes and materials, supporting the appropriate selection of O-rings in terms of both material and size. * Various types of fluororubber, including FEPM, are the specialty of Sakura Seal Co., Ltd. * We also accommodate shapes other than O-rings.
