*The inner diameter of the mouth of 25A or less is R-processed.

<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.
