※1. Each displacement amount is the value when each is displaced independently.
※2. Displacement for slanted piping differs from the above values, so please contact us each time.
※3. Weight is a guideline.
※4. The inside diameter of the mouth of 25A or less is R-processed.
Option

<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.
