Hayward SX200Z4PAK2 — Valve/Union O-Ring Kit (2-Pack)
The Hayward SX200Z4PAK2 is an OEM replacement kit containing two O-rings, used for sealing valves or unions on various Hayward pool filter and valve assemblies. These O-rings restore watertight seals and ensure proper plumbing performance by preventing leaks at union connections.
Key Features
- Includes two replacement O-rings — suitable for valve or union fittings.
- Factory-spec tubing/valve seal — designed to match original Hayward dimensions for leak-free performance.
- Compatible with many Hayward filter and valve models, including sand filters, cartridge filters, DE filters, and slide/Vari-Flo valves.
- Simple, straightforward maintenance — O-ring replacement is often all that’s needed to stop leaks at unions or valve connections.
Specifications
- Manufacturer: Hayward Pool Products
- Part Number: SX200Z4PAK2
- Included: Two O-rings (valve/union style) per pack
- Use With: Hayward sand filters (S200, S240, ProSeries, ProSeries Plus), cartridge filters (Super StarClear series), vertical-grid DE filters (ProGrid, MicroClear), slide valves (SP0410X), Vari-Flo valves, and other compatible valve/union fittings.
- Purpose: Replace worn or damaged O-rings to restore proper sealing on unions and valves
When & Why to Use It
Use the SX200Z4PAK2 kit when your filter or valve union shows leaks, fails to seal properly, or you observe water seepage around connections — a common maintenance need as O-rings age, dry out, or degrade from chemical exposure. Replacing the O-ring often restores a tight, leak-free seal without needing to replace the entire valve or union assembly.
Installation & Maintenance Tips
- Shut off the pump and relieve system pressure before disassembling or resealing unions.
- Remove the old O-ring carefully and clean the seating groove thoroughly.
- Lightly lubricate the new O-ring with a pool-safe silicone lubricant (not petroleum-based).
- Reassemble the union or valve, tighten per manufacturer guidelines, and test for leaks after filling water.
- Inspect O-rings annually — replacing them as part of routine maintenance can prevent unexpected leaks and prolong valve/laterals life.
