Aumzong Filter Tank Clamp Ring R0357400 for Zodiac Jandy CV/CL & DEV/DEL Filters — Aluminum, Tool-Free Knob

The Aumzong R0357400 Filter Tank Clamp Ring is a direct replacement clamp with a manual knob and durable aluminum construction, designed to restore a secure, leak-resistant seal on compatible Zodiac Jandy CV/CL and DEV/DEL pool and spa filters.

If your cartridge or D.E. filter is showing signs of leakage, a worn clamp ring or a failing knob can be the culprit. This replacement ring is built to match the OEM fit for specific Zodiac and Jandy filter models, delivering mechanical locking, corrosion resistance, and quick tool-free service. It comes paired with the corresponding O-ring part (R0357800) so you can refresh the tank sealing surfaces for reliable operation.

Which filter models will this clamp ring work with?

This clamp ring is compatible with a range of Zodiac and Jandy cartridge and D.E. filter series, offering a straightforward swap for original parts. It fits the CV and CL cartridge filters and the DEV and DEL D.E. filters listed by the manufacturer.

• Compatible cartridge models: CV340, CV460, CV580, CL340, CL460, CL580.
• Compatible D.E. models: DEV48, DEV60, DEL48, DEL60.
• Matches original mounting geometry for a direct replacement without adapters.

How does the knob and locking mechanism make maintenance easier?

The ring uses a manual knob and a mechanical lock so you can open and close the filter tank without tools. That simplifies routine checks, cartridge changes, and filter servicing, reducing downtime and the need for extra equipment.

• Tool-free knob lets you tighten or loosen the clamp by hand.
• Mechanical locking ensures the clamp stays secure under pressure.
• Speeds up routine filter disassembly for cleaning or element replacement.

What materials and build quality can I expect?

Constructed from a high-strength aluminum alloy, this replacement ring resists bending and corrosion common in pool environments. The material choice balances weight, rigidity, and long-term durability for reliable sealing under operating pressure.

• High-strength aluminum alloy resists deformation and corrosion.
• Precision mating surfaces match factory dimensions for proper sealing.
• Designed to withstand the forces inside pressurized filter tanks.

What maintenance steps improve longevity and prevent issues?

Keeping the knob and sealing surfaces lightly lubricated and inspecting the O-ring regularly helps maintain smooth operation and prevent leaks. Simple periodic checks reduce the chance of stiffness or seal failure over time.

• Inspect the O-ring (R0357800) and replace if cracked or flattened.
• Apply a small amount of silicone grease to the knob every few months.
• Check torque and seating after first use and during seasonal maintenance.

Who is this for: Pool and spa owners, service technicians, and maintenance teams who need a dependable, OEM-compatible replacement clamp ring for Zodiac and Jandy CV/CL cartridge filters or DEV/DEL D.E. filters. If you want a long-lasting aluminum clamp that restores a secure seal, permits tool-free access, and pairs with the correct O-ring for a complete tank service, this part is designed for you.
