Under Sink O-Rings 10″ x 2.5 – 2 PACK


O-Rings are used to seal the water filter housing cap to the water filter housing sump to prevent leaks. It is important to lubricate your o-ring with food grade silicone grease.

  • 2x o-rings for standard 10″ filter housing (undersink/twin blue filter)
  • Recommended replace o-ring every 2-3 years

If you do not know the size of your system’s o-ring, open the filter housing and measure the diameter of the o-ring. Your housing determines your o-ring size and not the filter that is used inside your housing.
