About This

  • ✅ MATERIAL SAFE TO USE: Our replacement O-rings (also called seals or gaskets) are composed of silicone rubber, which is sturdy and long-lasting; the rubber substance makes them soft and resistant to deformation, as well as safe to use.
  • ✅ EXTENDS LIFE AND ALLOWS FOR FAST TROUBLESHOOTING: Because your O-ring may gather hard water minerals, become pinched or twisted during installation, or expand/shrink when under water pressure, replacing it every third filter replacement is suggested.
  • ✅ LEAK IN THE SEAL: Can be used in conjunction with any food-grade lubricant to provide your water filter with the best leak seal. (It's worth noting that the O-ring should be replaced every 1-2 years.). Our gaskets are constructed of high-quality, long-lasting rubber.
  • ✅ EASY TO SET UP: To finish the installation, only use the wrench given by the system to remove the filter bracket, apply silicon grease to the O-ring, insert the O-ring on top of the old O-ring, and then screw it back in place.
  • ✅ GREASE/LUBRICANT COMPATIBILITY: Compatible with Big Blue Water Filters Size (3 Pack) Size o-rings are approximately 5.5" Inside Diameter x 5.83" Outside Diameter x 0.165" Thickness There is no need for grease. Install the O-rings after wetting them with water. If desired, silicone is compatible.
