Option
| Standard | option | |
| Flange standard | JIS 10K | Tap water F12, JIS 5K, JPI class 150, etc. |
| Flange material | SS plating | SUS304, SUS316, etc. |

<Caution>
Since the elongation when pressurized is greater than that of the conventional flexible (FF), please use a tie rod for thrust prevention if necessary.
<Remarks/Precautions>
- If the fluid is gas, the maximum working pressure will be 1/2 of the above value.
- Please contact us for non-standard specifications (diameter, length, etc.).
- Due to the manufacturing method, the plating on the flange may be discolored or mottled, but this does not affect performance.
