Product details
The Hayward CX900H is the o-ring for the Star Clear Plus locking knob. It is the genuine Hayward part, made in rubber.
What it fits
Hayward lists it for the Star Clear Plus cartridge filters: C751, C900, C1200, C1750 and C1900.
When to change it
Rubber hardens and takes a set, and once it does the knob area starts to weep. Because the o-ring costs almost nothing, it is the sensible first thing to replace, and a good part to have on hand before you open the filter to clean the cartridge.
