Hayward DEX2400Z5 — Outlet Elbow O-Ring
The Hayward DEX2400Z5 is an OEM replacement outlet-elbow O-ring used in certain Hayward pool filter systems. It provides a watertight seal between the stand pipe (center tube) and the filter manifold or outlet elbow — preventing leaks or bypass during filtration and backwash cycles.
Key Features
- Designed for use in Hayward DE filters (e.g. Pro-Grid, Micro-Clear) and compatible cartridge/sand filters using the same manifold design.
- Precision molded rubber seal to ensure leak-free joint between standpipe and outlet manifold or elbow.
- Simple, cost-effective replacement — restores proper sealing when original O-ring becomes worn, cracked, or flattened.

When to Replace
Replace this O-ring if you observe leaks from the outlet elbow, reduced flow during filtration or backwash, or sand/DE bypass in DE filters — signs that the seal is compromised or no longer seating properly.
Maintenance & Installation Tips
- Always depressurize and drain the filter before disassembly.
- Remove the old O-ring and clean all sealing surfaces thoroughly of debris and deposits.
- Apply a thin layer of pool-safe silicone or PTFE lubricant to the new O-ring before installation to improve seal life.
- Reassemble carefully and verify there are no leaks during a low-pressure test before returning to normal operation.
