Hayward SPX0704HA Key O-Ring Set

What This Part Is Used For
The SPX0704HA key O-ring set is used inside compatible Hayward multiport valves to seal around the internal key assembly. These O-rings help prevent water bypass within the valve body.

Why This Part Matters
Worn O-rings can allow internal leaks that reduce filtration efficiency. That may cause water to bypass to waste or lower return pressure. Replacing the set restores proper sealing and control.
