Quick overview
- Genuine Hayward Factory part SPX1480C, not a generic nut.
- Union nut only This is the nut on its own. Sealing o-rings and gaskets are separate parts.
- Listed for the S240 Hayward lists it for the S200 and S240 side mount sand filters.
- Also used elsewhere The same nut appears in the Pro Series side mount and Perflex DE filter parts lists.
- Hand tighten Union nuts on filter plumbing are meant to be pulled up by hand against the seal, not driven with a wrench, which is what cracks them.
- Common failure point Nuts crack at the thread or the flange after years of sun and over tightening, and a cracked nut will not hold a seal no matter how new the o-ring is.

Product details
The Hayward SPX1480C is the union nut used on the S240 side mount sand filter. It is the genuine Hayward part, sold as the nut alone.
What it does
A union lets you break the plumbing at the filter without cutting pipe. The nut is the piece that threads over the joint and draws the two halves together against the seal. All of the clamping load sits on it, which is why it is the part that fails: years of sun make the plastic brittle, and a nut that has been cranked with a wrench eventually splits at the threads or the flange.
Fitting
Pull the nut up by hand against the seal. If it will not hold without a wrench, the problem is the seal or the mating face, not the amount of force. The o-ring and the filter gasket are separate parts, and it is worth replacing the seal while the joint is open.
Hayward lists this nut for the S200 and S240 side mount sand filters, and it also appears under the Pro Series side mount and Perflex DE filter parts lists. Compare the part number stamped on your old nut before ordering.
