This O-RING-SET contains three 3.5" standard industry size O-RINGs to prevent leaks when you change your RO filters. Standard under sink reverse osmosis system. Recommend to change all O-RINGs once you've opened the housing. Lubricate with clean lubricant and place in grooves below threads to protect against water leaks.

Would buy again. Fit well in my RO sumps and good quality thickness.
