They work fine but these should really be included with the filter cartridge since they recommend replacement with every filter change. I rank these high though because after a year on the system, they still looked like they were brand new and could be used again. I still changed them just because they are cheaper than a flooded house and not worth the risk.

These Rings fit Apex type A housing but $5 for the little squeeze of Grease is a joke you can buy the O-rings themselves for $7 but definitely use Grease
