  • Dirt
  • Particulates

  1. Each time you replace your filter, clean and inspect the o-ring in between the housing cap and sump. If there is any damage to the o-ring, you need to replace it
  2. After cleaning the o-ring, apply silicone lubricant, like OR-LUBRICANT-SM
  3. You must use a silicone food grade lubricant. All other types of lubricant could damage the o-ring. Silicone Lubricant prevents leaking and extends the life of the o-ring
