O-ring, 13.6 x 2.4 mm – Viton, Part# 2122035

This O-ring is a direct replacement for Edwards part number 2122035. The cross-reference number for this part is OV-0660 . It is made from Viton material. You may also hear it called FKM, FPM, or Fluoroelastomer.

This specific size (13.6 mm x 2.4 mm) is used on the Edwards E1/E2M pump family . This includes the following pump models:

• E2M28

• E2M30

A similar O-ring of the same size (13.6 x 2.4 mm Viton, Part #02120035) is used on the E1M18 and E2M18 pump models . If you are servicing those pumps, you would need that different part number.

These are two-stage rotary vane pumps used in laboratories and industrial applications. They are known for delivering high ultimate vacuum and reliable performance. If you own or service these pumps, this is a seal you should keep in your spare parts box.
