Product details
The Pentair 071660Z is a 4-40 set screw, 1-1/8 inch long, used across the Purex WhisperFlo and IntelliFlo pump families. It is sold individually and two are required per pump.
Why the exact part matters
A 4-40 thread at 1-1/8 inch is an odd combination. Too short and the screw does not engage far enough to hold under vibration; too long and it bottoms before it clamps. Neither failure shows itself immediately, which is how a substituted screw ends up backing out weeks later on a pump that runs every day.
Where it is used
Pentair lists 071660Z in the parts breakdowns for the WhisperFlo, including the WF and WFE models, the WhisperFlo VS and VST, and the IntelliFlo Variable, VF and VS+SVRS. It also appears in the Sta-Rite IntelliPro VS+SVRS variable speed breakdown.
Ordering
Because the price of one screw is trivial next to the trip back to the equipment pad, order both at once if the pump is due for service and buy a spare while you are at it.
