Hihitomorrow CX900G Locking Knob & CX900DA Pool Filter Knob Kit for Hayward StarClear Plus

Product overview

The Hihitomorrow CX900G Locking Knob & CX900DA Pool Filter Knob Kit is a rebuild-friendly replacement designed for Hayward StarClear Plus cartridge filters. It targets common wear points in models across the C751, C900, C1200, C1750, C1900, and C2002 families, helping you maintain an efficient filtration system.

Why this kit stands out

Cartridge filters rely on precise seals and secure connections. This kit bundles seven critical components into one package, providing a practical path to replace worn parts rather than scrubbing away days of frustration. The result can be a smoother maintenance flow and less downtime on non-sunny pool days.

• Compatibility across StarClear Plus models: C751, C900, C1200, C1750, C1900, C2002.
• Seven-piece rebuild set: locking knob, lid O-ring, two washers, an O-ring, a guide cone, and an E-ring.
• Durable materials: high-quality plastic and rubber with a corrosion-resistant steel E-ring for long-lasting performance.
• Simple, user-friendly installation: designed for straightforward replacement with common hand tools.

What you get and how it helps

Inside the kit you’ll find everything needed to refresh a tired knob and seal system. The CX900G locking knob delivers a reliable grip that accepts a full range of routine adjustments. The lid O-ring and additional O-ring work together to maintain a tight seal, while the washers and guide cone align and cushion each interface. The steel E-ring adds durability against rust and wear.

• 1 locking knob (CX900G) for a secure, user-friendly replacement.
• 1 filter head lid O-ring (CX900F) for a dependable seal at the top of the head.
• 2 washers (CX900WPAK2) to ensure proper spacing and fit.
• 1 O-ring (CX900H) to reinforce leak prevention.
• 1 guide cone (CX900D) to help alignment during reassembly.
• 1 E-ring (CX900J) for lasting retention.
• All pieces combined support a rebuild approach rather than a full filter replacement.

Real-world use cases

Pool owners commonly perform seasonal checks or weekend maintenance. This kit is a practical option when you notice looseness, minor leaks, or inconsistent knob operation. It’s a quiet, satisfying upgrade that can restore a smooth feel when turning the knob and reduce fiddling with worn components in between cleanings.

Installation tips

• Shut off the pump and drain the system before you begin.
• Follow the included guidance to remove the old parts and seat the new components.
• Turn the top cover to the front side and secure the knob clockwise to finish the setup.
• Check for secure seating and a clean seal before resuming operation.
