Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Poolaroo Pro Tip

The EQ500, EQ750 and EQ1000 all use this same screw, so one part number covers any of the three pumps. Match your pump's model number to the Fits Into table, then order 4 screws per pump so the full set is identical in thread, length and 18-8 stainless material.
