Should I put some silicon grease on the o-ring when replacing, or even add some every so often to help cut down on leaks or extend life of o-ring? Thanks

I would advise to use a specific o ring lubricant. Click here to view probably one of the more common types. Yes this would help extend the life of the o ring and help seal.

Hello Charles, the oring goes between the cover and the cap cover. Attached is the parts breaks down so it would be Key 4A and 5A

How often is normal for the replacement of this O ring. It seems to stretch past usefulness in a years time.

A  Answered on 4/4/2016 by InyoPools Product Specialist Alan M.

Hello Stephen, There isn't a specific lifespan for the chlorinator o-rings. I would highly recommend using a this lubricant, Magic Lube O-ring Lubricant, to help extend the life of your o-rings.

I need a new Oring on the cover of my Hayward Chlorinator, but can't tell what the model number is. Can you help?

Hello Thomas, yes that would be the correct oring or you can order the Hayward CL200 Tune Up Kit - APCK1052.
