R0357500 Clamp Ring Knob Assembly w/ Threaded Rod For Zodiac CV CL Jandy Filter

Clamp Ring Knob Assembly for Zodiac CV/CL and Jandy Filters

This clamp ring knob assembly with threaded rod (OEM cross-reference R0357500) secures the filter tank band clamp on select Zodiac CV and CL series and Jandy pool filters, ensuring a watertight, vibration-resistant seal.

Overview

The clamp ring knob assembly replaces the factory knob and threaded rod that tighten the tank band clamp around Zodiac and Jandy pool filter lids. A secure clamp prevents leaks and maintains correct pressure during filtration cycles, making this assembly critical for routine cartridge cleanings and seasonal startup. Designed as a straightforward swap for worn or broken components, it restores the filter’s seal without needing a full clamp replacement.
