Seal Type
Pressure
GENERAL/SFE 0-689.5 bar
CARBON
0-1379 bar
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 bar
TEMPERATURE
This seal is best suited for applications which require higher temperatures. Its chemical
compatibility is similar to that of the general seal.
LOW 0-137.9 bar
PRESSURE
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. Refer to Section 9.10.2
"Piston Seal Break-In (Aqueous Seals Only)".
AMMONIA (NH ) 0-275.8 bar

The standard seals for each pump model satisfy the requirements of
most applications, including those that use carbon dioxide, such as
SFE. However, certain solvents and/or conditions require special cyl-
inder seals to facilitate the application. Table 2-6 "Seal Selection
Chart" is provided to assist in selecting the correct seal for your pump
and application requirements.
