We carry O-rings for the ProSeries Reverse Osmosis systems. When it comes to O-rings, a small leak can lead to big problems. When checking for leaks in housings, O-rings should be replaced when changing the reverse osmosis filters to avoid possible water leakage that can lead to big damage.
O-rings are essential for leak-free performance, the help seal the housings so the water stays where it should, however over time they do deteriorate. Regular replacement of your housings O-Rings prevents leaks which can cause a lot of damage. It's always recommend to change all O-rings once you open the housing. Clean the grooves and use a silicone lubricate with below thread to prevent water leaks as well, when replacing your O-Rings.
