Description
The 10" and 20" reverse osmosis system housing wrench pairs perfectly with our larger 4.5" diameter "Big Blue" housings. These wrenches are best for loosening stuck housings,
If you have one of our pro-series systems, you'll want the slimline wrench
(These wrenches are for loosening hard-to-access housings, not for tightening. You will want to hand tighten to avoid crimping the O-ring, creating micro tears in the threading, and eventually leaks.)
