Find the Right Pentair FNS Plus 48 Replacement Part

Select a diagram number to see its OEM part number and available choices. When a number lists several parts, compare the exact model and source notes before choosing.

Which model and source edition does this page cover?

Each source edition keeps its own parts and callouts. Use the equipment nameplate, installed components and cited manufacturer document to confirm the correct reference. A shared callout or similar description does not establish interchangeability.

What if my part has no Add to cart button?

Use the call or text option and include the OEM part number and equipment model. Manufacturer required quantity and the retail selling unit are separate; confirm the product package before ordering.
