Jandy Tank Clamp Ring with Knob Assembly (R0357400)
The Jandy R0357400 Tank Clamp Ring with Knob Assembly is an OEM replacement band clamp that secures the upper and lower tank halves on select Jandy cartridge and D.E. pool filters. A properly tightened clamp helps maintain an even, reliable seal at the tank O-ring and allows safe access to the filter internals for cleaning and service.

- Jandy CL Series Cartridge Filters: CL340, CL460, CL580

What’s Included
- Tank clamp ring (band clamp)
- Threaded rod and knob hardware for tightening/loosening
Common Reasons to Replace
- Clamp is bent, cracked, or corroded
- Knob/rod threads are stripped or won’t tighten evenly
- Tank halves shift or won’t stay aligned during tightening
- Recurring tank seepage after the O-ring is confirmed good and properly seated
Installation Notes
- Turn off the pump and relieve all filter pressure before loosening the clamp.
- Clean the clamp contact surfaces and confirm the tank O-ring groove is free of debris.
- Seat the tank halves evenly, position the clamp uniformly around the seam, then tighten gradually to an even fit.
- After start-up, check for leaks and re-check clamp alignment once the system is running.

Installation & Maintenance Tips
- Always relieve pressure at the air relief valve before opening the tank.
- Keep the tank seam and O-ring groove clean—dirt and sand can cause uneven sealing.
- Inspect the tank O-ring for flattening, nicks, or stretching whenever the filter is opened.
- Hand-tighten evenly and avoid overtightening; uneven clamp tension can cause misalignment and leaks.
- After reassembly, run the system and inspect the seam for drips; shut down and re-seat if needed.
