ARG J-Style Filter Manifold | FMR0359
ARG FMR0359 J-style upper filter manifold. Replaces a worn hub to restore even flow, correct element seating, and seal integrity. Verify fit by parts diagram.
Features
- Direct replacement J-style upper manifold/hub
- Helps prevent internal bypass and channeling for consistent filtration
- Stable element seating reduces leaks and short cycling
- Drop-in install when tank, standpipe, and body are sound
- Ideal during full grid/cartridge service or leak/pressure troubleshooting
Description
The FMR0359 takes the load and alignment duties at the top of the element pack. When the original hub is cracked or warped, the grid or cartridge set won’t seal evenly and water follows the path of least resistance. Replacing the manifold brings back uniform distribution across the elements, steadier pressure, and better clarity between service intervals.
Pro Tip
Check the standpipe and manifold O-ring surfaces while you’re in the tank. Replace flattened or nicked seals and tighten plastic hardware evenly—over-torque leads to future leaks.
