Mezvion Air Gauge Release Valve Assembly for Jandy/Zodiac Cartridge Filters — R0357200, Integrated Pressure Gauge & Tool-Free Inst

Mezvion R0357200 is a replacement air-release valve assembly with an integrated pressure gauge that vents trapped air and lets you monitor cartridge-filter pressure. The Mezvion R0357200 Air Gauge Release Valve Assembly is a direct-fit component designed for cartridge pool and spa filters from Jandy and Zodiac model families. It combines a venting mechanism with a pressure gauge so you can quickly purge unwanted air, check system pressure at a glance, and keep circulation running efficiently. Built for chemical resistance and simple tool-free installation, it replaces several OEM part numbers and brings reliable operation to older or maintained filtration systems.

How does this valve assembly remove trapped air from my filter?

The valve has a purpose-built release port that allows air pockets to escape from the filter housing without interrupting water circulation. Releasing trapped air prevents pressure spikes and maintains proper water flow through the cartridge, which helps your pump run smoothly.

• Manual vent button for controlled air release
• Clear pressure readout to confirm normal operation
• Seating and seals designed to avoid leaks during venting

Which models and part numbers is this compatible with?

This assembly fits multiple Jandy and Zodiac cartridge-filter lines and can substitute a number of legacy part numbers. Use it when replacing worn vents or when a matching OEM part is unavailable.

• Works with Jandy/Zodiac series: CV340, CV460, CV580, CL340, CL460, CL580
• Also fits DEV48, DEV60, DEL48, DEL60, JS60-SM, JS100-SM series
• Interchanges with R0357200, 4580-003, 17-295-1062 and other listed numbers

How accurate and durable is the built-in pressure gauge?

The integrated gauge delivers reliable pressure readings so you can spot filter clogs and determine when cartridge cleaning is needed. The gauge body and materials are chosen to withstand exposure to routine pool chemicals and outdoor conditions.

• Easy-to-read dial for quick system checks
• Chemical-resistant construction for longer service life
• Sealed mounting to protect the gauge internals

How easy is installation and maintenance?

Installation is straightforward and typically requires no special tools; the valve threads or snaps into the filter head following manufacturer guidelines. Routine maintenance is limited to occasional cleaning and checking seals to preserve proper venting and gauge accuracy.

• Tool-free or simple-threaded replacement on compatible heads
• Quick swap for worn or leaking vents
• Minimal upkeep: inspect seals and wipe the gauge face
