Kitchen Canister Housing O-rings.  Order every 4 years.

Manufacturer recommendation is that you replace your undercounter filter sump every 5 years.  That includes new canister O-rings.  Order new sumps and you don’t need to order these.

Sold individually.  Select the number you need for your kitchen filter; one for each canister. If you have a 2-canister, get 2. For a 3-canister, get 3.
