Wrench for 10" & 20" x 4.25" Canisters (Big Blue)
$12.99

Wrench to tighten and loosen reverse osmosis canisters. 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.
