Review on 🧴 Bottle Jack/Floor Jack Oil Reservoir Rubber Filler Plug Bung, 12PCS - Horizontal Jack Bung for Hydraulic Jack Oil Reservoir Filler Hole, 8mm by Steven Darkshnar

Over the years I have had to add hydraulic oil to a few of my jacks. Unfortunately, when attempting to remove the filler plugs, the plugs became two-piece devices. I tried to find a fork but it never worked. You just have to use the right connector or it just won't work. These are the right stubs that solve the problem. Well, that and a YouTube video that explains exactly how to properly fill and bleed the ports (a very simple process actually). Now all my jacks are functional again.
