These rings – along with three replacement filters and the food grade lubricant – were recommended as part of an annual replacement of three of the 5 filters used in the system. Our system is just over 1 year old and the original seals showed no signs of leakage or of any weak/thin/worn areas. The replacement rings and filters fit perfectly and I do not expect that they will have any issues before their next annual replacement.

New O rings will ensure leak free operation until next filter change. Super customer service made the purchase easy

I bought this to replace the previous o set I got for my RO water filtration system. It fit just fine.

Save yourself the headache of having a leak by using the old gasket. If the old gasket black-stains your gloves or skin, it must be replaced. Apply food grade silicone grease on the gasket at installation.

The CS of this O ring is smaller than the original. Therefore, it did not fit in the housing

i’ve had my unit for about 10 years this is the first time i’ve had to replace them good quality for money

when replacing the water filter cartridges, it’s a good idea to replace the o-rings that seal the housings. The o-rings become compressed over time and can fail if neglected.

The nominal cost of the replacement gaskets makes the decision to replace them when changing filters a no-brainer. Why take a chance on the headaches caused by a leak? New gaskets – no leaks – no headaches!
