The GE WS60X10005 Silicone Tube is a food-grade silicone grease used to prevent leaks and improve sealing in conjunction with your o-ring. The WS60X1005 contains 0.1 oz or 3 grams of lubricant.
Although this lubricant is a GE product it can be used with all different brands of water filtration systems and o-rings. This tube of silicone lubricant should be enough to lubricate up to 10 o-rings.
