TmallTech 10" inch Reverse Osmosis Water Filter Canister Housing Wrench RO Filter Housing

The one that came with the unit got old and snapped. Ordered these undone it not problem and it was vey tight!

works as expected

While I did get the cartridge open, it only fits half way up (definitely not near the top like the photo) and therefore you have to be careful of the angle that you twist at to prevent any damage to the rest of the unit.

Does what it says on the tin!

Very flimsy - you need 2 of them if your filter is stuck as single one will bend and most likely you will fail to undo your filter

Quality good

Qualitativamente può andare, il prezzo è buono. Consigliato

I have an APEC 5-stage RO water filter system under the sink, for 3 years now. For some inexplicable reason, APEC includes a half-wrench, instead of a full wrench, for you to "open" and "close" the filter casings (see picture with the half-wrench on the left, this product on the right). My first impression was Oh boy, how is this going to work?, but then, after the first year, somehow I managed to change the filters using that thing. This year, I couldn't get close to believe that I was getting close to start opening any of them! I would like to meet the “engineer “ that said “Sure, that works just fine! We’ll save $0.05 in plastic by leaving only half wrench!” It might have helped that a year ago, it was changed by professional plumbers, and it seems they didn't want anyone to ever open them again, not even them. The half wrench kept slipping every single time, not even a little torque was applied and it was almost instantly off. And then I searched and among several choices, I picked this. It was an instant game changer. The thing opened each of the casings at the first try. It also tightened them up without slipping or skipping. The size is slightly bigger (see pictures), but it definitely works with the APEC RO system. Pretty simple, pretty cheap and pretty good. It makes the half-wrench fiasco even more mind blowing. Highly recommended.

This was so handy. It helped me open up the water canister that even with my sister helping we could not budge. Best lever ever.
