Q: I'd like to verify the size of these -rings before I order: diameter and thickness. I need to replace the O-rings on the unions for my circupool salt cell. I purchased the RJ30N "plus" unit in April, 2016.Can you provide the dimensions please?
A: These oring are for CORE-Series salt chlorinators. If you look under Replacement Parts > RJ Plus Series, you'll see the o-ring set that you want.
