Replacement O-rings For Slim Line, Big Blue And Standard Water Filter System Housings

Dow 111 Silicone Sealant And Lubricant For O-rings
If you do not know the correct O-ring size for your system, you will need to open the filter housing to measure the diameter of the O-ring.   The same filters fit in different size filter housings using different size O-rings.   The O-ring size is not tied to the filter, but to the filter housing.
