Nexx Filter Cover with Oring Fits All API & Rena Nexx Filter Systems

The blue cover locks into the top of the filter chambers on the Nexx Filter. Replace if broken or the o-ring fails and the cover leaks after the filter handle is in the lock position. Works with both the standard cartridge holder or with bag media. These are direct from the manufacturer but do have some surface scratches. The Orings are brand new and could be used on other covers if they are in better condition. The best way to remove the oring from the cover is to use a thin bladed table knive, thin screwdrive blade or the end of a paperclip. Slide in on edge of the orig and pry up and remove with your fingers if possible.
