The Berkeley S26471 O-ring is a replacement sealing component for the specified mechanical-seal pump configurations below. It measures 2-11/16-inch inside diameter by 2-7/8-inch outside diameter, with a 3/32-inch cross section.
S26471 fits the O-ring position associated with the mechanical shaft-seal retainer in these assemblies. It is a different service item from the mechanical shaft seal and the larger pump gaskets. Select the exact part number and location, rather than replacing it with a similar-size O-ring without checking the application.

| Check | What to confirm |
|---|---|
| Pump configuration | Confirm the complete model, catalog number and existing O-ring location. |
| Operating conditions | Confirm suitability for the pumped liquid and operating temperature; size alone is not a material specification. |
| Related parts | Check the seal retainer, mechanical seal and gaskets separately; this is not a seal-service kit. |
