Dow Corning 111 valve lubricant and sealant. Meets FDA 21 CFR 175.300. The o-ring sealant package contains 0.2 oz of lubricant. Use this o-ring Silicone Grease on all brands of Water Filter Housing O-Rings and all Reverse Osmosis System O-Rings. O-Ring lubricant prevents leaks and improves sealing of the o-ring. 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 them 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 o-ring.
