RO Canisters can become very tight over time and changing filters can be a real challenge if you do not have the correct filter wrench. These are very handy to have around and are made of strong plastic to last just as long as your Reverse Osmosis system.
Wrench for 10" 2.5" Canisters - This is the same wrench that is supplied with all BRS RO/DI systems and is by far the most common size for residential reverse osmosis systems and works with almost all canisters that use 2.5" x 10" filters.
Wrench for 20" x 2.5" Canisters - The 20" Wrench fits a majority of canisters that use 2.5" x 20" reverse osmosis filters.
Wrench for 10" x 4.25" and 20" x 4.25" (Big Blue) Canisters - If you have a jumbo reactor almost any "Big Blue" canister this is the wrench you want. It is compatible with most canisters that use 4.25" x 10" or 4.25" x 20" filters.
Wrong Wrench By Tony on 10/28/2017Tony wouldn't recommend this product to a friendOrdered wrench based on dimensions provided on the website and what I received was not the right wrench. Totally different dimensions then what the website advertised. Completely disappointed.

Necessary tool! By Josh on 2/7/2012Josh would recommend this product to a friendThis is a great tool. Make sure your canisters are tight and easy to loosen when needed. Worth every penny!
Must Have By Jim on 6/24/2011Jim would recommend this product to a friendI bought a RO/DI filter system from another manufacturer that came with a half circle wrench. This one is much more secure and makes servicing the filter easier.
Ask a question
I'm afraid we're not familiar with the Chemflo RO systems. Typically home units will use 10" filter elements and the housings are sized accordingly. The wrench for standard canisters refers to the canisters we use for the 10" x 2.5" filters and housings.
