DIOXIDE
This is our standard seal. It is good for most applications, particularly those using organic solvents,
such as: LC, SFC, and SFE.
HIGH 0-689.5
TEMPERATURE bar
This seal is best suited for applications which require temperatures between 50°C and 100°C. Its
chemical compatibility is similar to that of the general seal.
LOW 0-137.9
PRESSURE bar
This seal may provide better sealing at lower pressure. Its chemical compatibility is similar to that of
the general seal.
AQUEOUS 0-689.5
bar
This seal has better wetting properties, making it a good choice for aqueous solutions.
It is also the best choice for electrochemical detection.
Note: This seal requires a special break-in procedure before installation. See Section 9.9.2.
