OEM locking knob used on all Hayward StarClear Plus cartridge filters except the 175 sq ft model (see 4663-09 for the 175 sq ft knob).
This knob locks the filter head in place.

also ineed rubber o ring that goes between top and bottom half
My initial threads have failed on this Filter Lock Knob and the rod that screws into the bottom unscrews. If I replace this knob, how do I get the rod to stay screwed into the bottom when I remove the lid?
Hi, Joe. You will need to use Thread Lock.
I have a C1200 and the threads in the locking are stripping. Will this part work as a replacement?
