Pentair Sta-Rite 2 in. valve star seal – 14971-SM20E12

The Pentair 14971-SM20E12 spider gasket, also called a spider gasket, is a replacement part for certain 2 in. Sta-Rite multiport valves. It separates the valve's internal passages to direct water according to the selected position.

A part to check in the event of an internal leak

A worn, detached, or damaged spider gasket can allow water to pass into a circuit that should be closed, such as the waste outlet during filtration. Replacing it may restore a valve whose other components are still in good condition. A diagnosis is still necessary: the gasket is not the only possible cause of a leak.

Confirm your valve's part number

The part number 14971-SM20E12 appears in the Pentair catalog for the Sta-Rite 14971-TM-22-L valve and for certain versions of 2 in. side-mount valves. Check the parts diagram that exactly matches your valve. The mention “2 in.” refers to the nominal valve size and does not correspond to the gasket's outside diameter.

Piscine Hippocampe's advice for your parts

Before ordering, prepare a photo of the valve, its label, and the gasket to be replaced. Our Delson team can help you identify the correct part number. Also have the sealing surfaces and mechanism checked to avoid replacing a part that is not responsible for the problem.
