Quick overview
- Genuine Pentair The factory 35402-0074Z wing nut, not a hardware store substitute.
- 1/4"-20 thread Matches the standard thread used on this Sta-Rite DE filter hardware.
- Made to be hand tight A wing nut goes on and comes off by hand, which is what you want on a part you remove at every filter service.
- Series naming The catalog lists this fitment as both DES series and DEP series, so check the nut you are replacing against the thread.
- Corrosion is the usual reason These nuts live in wet chemistry, and eventually they seize on the rod or round off at the wings.
- Worth keeping a spare Small fasteners are easy to drop into the equipment pad gravel during a teardown.

Product details
The Pentair 35402-0074Z is a 1/4"-20 wing nut used on Sta-Rite DE filters. It is the genuine Pentair replacement for the hand fastener that gets removed and refitted every time the filter comes apart.
Why it wears out
A wing nut at the equipment pad lives in a wet, chemically aggressive spot and gets handled with wet hands at every service. Over a few seasons it corrodes onto its rod, and the wings round off when someone reaches for pliers. At that point the nut has to be cut or forced off and replaced, which is the situation this part exists for.
Before you order
The catalog carries two readings of the fitment: the product name lists the DES series and the manufacturer description lists the DEP series. Both point at the same family of Sta-Rite DE filters, so the safe check is the physical one. Confirm the thread is 1/4"-20 and that the nut in your hand matches the one shown here.
