Jsyfcfc CX900G Locking Knob Kit for Pool Filters | Cartridge Filter Compatibility

Upgrade your pool filter maintenance with the Jsyfcfc CX900G Locking Knob Kit, designed to restore secure connections across a wide range of cartridge filters. This thoughtfully assembled kit bundles durable replacements for the most frequently used parts, helping you refresh the heart of your filtration system without hunting for spare components.

What you get and how it fits

The package includes nine pieces that cover critical points in a typical CX900G based setup: locking knob, guide cone, E-ring, two washers, an O ring for the filter head, a replacement pressure gauge, and a directional vent valve with its O ring. Together, these parts support a tighter seal, smoother assembly, and dependable operation with compatible models such as C751, C7512, C900, C9002(S), C1200, C12002(S), C1502, C17502(S), and C2002.

• CX900G Locking Knob: secure the cartridge in place.
• CX900D Guide Cone: aligns parts for trouble-free installation.
• CX900J E-Ring: helps maintain a reliable locking mechanism.
• CX900W Washers: enhance seals around critical joints.
• CX900H O-Ring: provides an effective gasket against leaks.
• CX900F Filter Head O-Ring: maintains the seal at the head interface.
• ECX271261 Pressure Gauge: enables quick pressure checks during maintenance.
• ECX1322A Directional Vent Valve with O-Ring: helps regulate airflow through the valve.

Materials matter: VMQ and EPDM plastics bring aging resistance, corrosion tolerance, and robust performance under heat. An electroplating process adds rust resistance, giving a more durable finish to metal like components while still allowing for easy disassembly when you service your pool.

Installation and setup made straightforward

To install, remove the old components and replace with the new parts. A compact pack includes a roll of plumber's tape 0.6 inches wide by 118 inches long to help seal threaded connections as you fit the pressure gauge. The gauge depth is designed for a proper seal based on your specific setup, so take a measured approach to tightening.

• Includes practical guidance on matching your model and ensuring proper sealing depth.
• Designed for smoother replacement, with clearly matched parts for quick reassembly.
