So I ordered a pair of standard reverse osmosis membrane housings and this wrench. I first bought this to open my old membrane case, but this wrench should work for my new case as well. So I checked my case and it has 13 lugs, this key has 13 notches. So I figured most of them would be the same diameter, but no, the normal ones are just a bit smaller and slip. I don't blame this key as it is an apec key. But just a warning to those who have bought cheaper reverse osmosis membrane housings, this key will not work.
