APEC Replacement O-Ring for ROES-50 3.5 OD Reverse Osmosis Water Filter Housings

The O-RING-SET comprises 3 pieces of 3.5-inch standard industry size O-RINGs, which are designed to prevent leaks when customers need to change the 3 pre-filters of a 10-inch standard under-sink reverse osmosis system. To maintain optimal performance, it is recommended to replace all O-RINGs every time the housing is opened. Before reassembly, the O-RINGs should be lubricated with a clean lubricant and placed in the grooves below the thread to prevent water leaks.
