Star-Clear Locking Knob
The CX250G locking knob secures the lid on a Hayward Star-Clear cartridge filter, keeping the tank sealed under pressure. It replaces a worn, cracked, or stripped knob that no longer holds the lid tight.
Compatibility
- Hayward Star-Clear Cartridge Filter C-250
- Hayward Star-Clear Cartridge Filter C-500
- Hayward Star-Clear Cartridge Filter C-750
- Hayward Star-Clear Cartridge Filter C-1000
Hand-tighten the knob only; over-torquing can strip the threads or crack the knob body. Check the lid O-ring at the same time, since a damaged O-ring will leak no matter how tight the knob is.
This product ships free via FedEx Home Delivery.
