<Remarks/Precautions>
- Hot water cannot be used.
- Since silicone rubber lacks wear resistance, its service life will be extremely short for fluids containing solids.
- 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.
- The maximum displacement in the performance table of each product is the value when each product is displaced independently.
