The O-ring cherry seal is made from a special material that excels in low adhesion, low friction, low sticking, and low outgassing properties, and is shaped into various sizes.
Fluorine rubber is the material that Sakura Seal Co., Ltd. excels at among many materials. Among them, the various types of Fluoro-Up are a series of special fluorine rubber that reduces rubber-specific properties such as adhesion and sticking. Unlike coating treatments like PTFE that lose their effectiveness immediately after use, the effects of Fluoro-Up last for a long time. In seals made of rubber, issues can arise due to friction resistance and adhesion in dynamic parts, or due to sticking in opening and closing sections, which can cause the sealing material to come off. The Fluoro-Up series contributes to resolving such problems.

Line up（4）
| Model number | overview |
|---|---|
| Floro Up D | This material excels in low adhesion and low outgassing properties. It reduces sticking caused by prolonged contact and significantly decreases hydrocarbon and fluorine gases released from rubber due to surrounding conditions. Hardness A70±5. Black color. Temperature -20 to 230℃. |
| Floro Up K | This material greatly contributes to reducing friction resistance in dynamic parts due to its low adhesion. However, it has high gas permeability, making it unsuitable for use in high vacuum conditions. Hardness A70±5. Black color. Temperature 0 to 230℃. |
| Floro Up S | This material possesses low adhesion, low friction, low sticking, and low outgassing properties. However, like Floro Up K, it has high gas permeability, making it unsuitable for use in high vacuum conditions. Hardness A70±5. Black color. Temperature 0 to 230℃. |
| Floro Up V | This material can be used in high vacuum conditions where Floro Up K and Floro Up S cannot be used. However, compared to Floro Up S, its low adhesion is slightly reduced. Hardness A75±5. Black color. Temperature -20 to 250℃. |
