Product details
The Pentair 350103 is the o-ring for the OptiFlo pool pump, listed with the parts for the 3/4 through 1-1/2 HP models. It is the genuine Pentair part.
Where it sits
The source lists this as the pot to volute o-ring, the seal at the joint where the strainer pot meets the pump volute. It is on the suction side of the pump, which is why it matters more than its price suggests.
What a bad one does
Anything upstream of the impeller that leaks does not drip, it draws air. A flattened, nicked or twisted o-ring at this joint lets air into the suction side, and the symptoms are a pump that will not hold prime, a strainer pot that never fills completely and air bubbling out of the returns.
Fitting
Clean the groove and the mating face before fitting, and use a thin film of silicone o-ring lubricant rated for pool use. Avoid petroleum based grease, which swells the rubber over time. Any time the pump is opened, fit a new o-ring rather than reusing the one that has been compressed in the groove for seasons.
