RO parts for sale
 

So I bought one of those ebay RO/DI units ages ago, I forget what it is called now. A lot of people on here have purchased them..

Anyways, I have the white cannisters which hang down for sale. 3 of them to be exact. Just the part that twists off. Maybe you dropped one, broke it etc. Here is a spare one for you.

5$ ea.
