Product details
The SuperPro G-418-9 is a generic valve seat gasket built to replace the Hayward SPX0740D. It is the part commonly called a spider gasket, and it is the seal that sits at the valve seat.
Generic versus OEM
This is a SuperPro made equivalent rather than a Hayward branded gasket. The Hayward number appears here so you can cross reference it against a diagram or a parts list. If your quote or work order calls for SPX0740D, G-418-9 is the SuperPro line item that answers it.
When to change it
Seat gaskets are rubber, and rubber hardens, flattens and eventually splits. A gasket that has taken a set no longer seals cleanly against the seat, and the usual result is water passing where it should be shut off. It is worth fitting a fresh one any time the valve is opened up, because the gasket costs very little next to the valve it protects.
