Pentair 39104500Z Union Nut C-Clip | Clean & Clear, Warrior Filters

The Pentair 39104500Z Union Nut C-Clip is a genuine OEM replacement retaining ring that secures the union nut on Pentair Clean & Clear, Warrior, EasyClean, and Predator series pool and spa filters. This small but critical piece of pool hardware prevents the union nut from backing off under high pump pressure, ensuring a secure, leak-free connection between your filter tank and plumbing.

🚩 PRO TIP

If you notice water seeping or leaking around your pool filter union connection, inspect the C-clip before replacing the entire union assembly. A missing, rusted, or deformed clip is often the root cause—and this affordable fix can save you a costly service call or plumbing overhaul.
