It prevents gaskets from sticking to metal and resists weathering and water washout.

  • Should I use a lubricant on my O-Ring?
    If you choose to reuse your water filter housing o-rings, you should use a lubricant on the o-rings to keep them effective. You should only use a special silicone lubricant.
  • Do I need to lubricate the gasket on the filter cartridge?
    Generally, no because each replacement filter cartridge comes with its own new gasket if one is needed. The rubber gasket is the top or bottom part of the replacement filter cartridge and is not the same as the oring.

  • O-Ring Silicone Lubricant Instructions:
  • First, wipe your old O-Ring clean. Then wipe the groove in the filter housing clean. Finally, apply enough lubricant on the O-Ring to give it a gloss. The ORing is ready to place back in the housing.
  • If the O-Ring is bent, crimped, or showing signs of wear, you should replace the oring.
