The Hayward SPX0704HA Key O-Ring Set is a replacement sealing gasket kit designed for compatible pool valve and control assemblies. This set includes multiple O-rings used to seal key interfaces and threaded components, helping prevent water leakage, maintain pressure stability, and support reliable operation during normal pool circulation and routine maintenance.
Key Features
• Replacement O-ring set engineered for sealing key interfaces in compatible Hayward valve systems.
• Provides multiple O-rings to create watertight seals at critical sealing points.
• Helps prevent water leakage and air intrusion in valve stems and threaded connections.
• Ideal for replacing worn, compressed, or deteriorated sealing gaskets during service.
• Constructed to withstand continuous exposure to pool water, chemicals, and outdoor conditions.
• Supports dependable leak resistant performance in routine maintenance tasks.
Product Overview
The Hayward SPX0704HA Key O-Ring Set contains essential sealing components used across various pool valve and control assemblies where O-rings are required to provide watertight interfaces. Installed around valve stems, keys, or between mating surfaces, these O-rings form compressive seals that help prevent water from escaping at joints and restrict ingress of air that could compromise pump priming or pressure balance in the circulation system.
Over time, O-rings can lose elasticity, crack, or degrade due to exposure to pool chemicals, temperature cycling, and repeated assembly and disassembly during maintenance. When sealing performance deteriorates, water leakage and reduced hydraulic efficiency may occur. Replacing worn or damaged O-rings with the SPX0704HA set helps restore proper sealing integrity, supports stable water flow and pressure, and contributes to the long term reliability of compatible Hayward pool systems. This replacement kit is commonly used during valve servicing, scheduled maintenance, or comprehensive rebuilds to ensure optimal leak free performance.
