I have the swim n play FC100 model cartridge filter unit & need the lid-O-ring for both the bottom section & top cover. My specific question here is will this lid-O-ring fit my model # FC100?

No, This o-ring will not fit your FC100 cartridge filter. Your FC100 crossed reference to the Waterway Clearwater Cartridge.

Hi Mike, This O-ring will not fit a C1750 filter. The Filter Head O-ring (CX900F) will be the correct lid o-ring.

I have a waterway proclean pccf-125, 44 x 16, 817-0125p. I have had leak problems where the top meets bottom. Your pix looks like mine but there was never an o-ring included. Are you sure this model needs one, and which? thanks

Hi Wayne, The PCCF filter need a Lid O-ring or else it will leak once the tank fills under pressure. If it's leaking now then you will need to replace it.
