Hayward SX200Z4PAK2 Valve O-Ring Set - Pack of 2

What This Part Is Used For
The Hayward SX200Z4PAK2 is a valve O-ring set used on compatible Hayward sand filter valve assemblies. These seals install at the valve connection points to prevent leaks while the system is running and during backwash cycles. This set is supplied as a pack of 2.

Why This Part Matters
Valve O-rings are a common leak source after a valve is removed for service or after seasonal winterizing. A bad valve seal can drip steadily, pull air, or create messy leaks during backwash. Replacing the correct O-rings helps restore a tight seal without over-tightening unions or clamp hardware. This is an easy fix that prevents repeat calls for a valve that keeps weeping.
