Sterling Seal APCAS201 3/4-Inch Pool Pump Shaft Seal

Replace a leaking or worn-out pool pump shaft seal with the Sterling Seal & Supply APCAS201. This standard PS-201 version mechanical seal fits 3/4-inch impeller shafts and provides a direct cross-reference for dozens of standard pool and spa pump models.

🚩 PRO TIP: Confirm that your pump requires a 3/4-inch impeller shaft seal and uses the standard PS-201 version. Note that the APCAS201 is a standard duty seal, not the heavy-duty Viton PS-3868 upgrade.
