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

I had to replace a lost jack fork. After researching bushing manufacturers I found this one on Revain and it fits perfectly. Tight closure without leakage.

This is a standard size semi-flexible hydraulic jack that fits several jacks I work on. It comes in a small clear plastic storage box and is very valuable to me.

If you're like me you lost your G@&*#@& plug trying to fill your fluid reservoir. These fit perfectly. A word of warning: if you lose plugs, you probably have too much liquid in your reservoir.

It fits a jack but differs from the factory flared end. The end on them is straight and big so a screwdriver helped insert it into the hole, everything seemed fine, will buy again if I lose 12 more times lol.

these little bottle jack plugs are hard to find. They fit very well and many of my friends have enjoyed them when I gave them a pair. I would like to find a seal on the valve. Hope this seller has them in stock. Fast delivery and great product

After releasing too much air from my Black Jack Lift through the plug, the plug broke and I was stuck without a heavy duty jack. These corks fit perfectly and Black Jack is back in business. It's good to have extras! They are not easy to find locally.

Although I initially thought the plug would not fit, it just takes a bit of work to get it into the filler hole. I had to push with a screwdriver. The part you insert is tapered, that helps. Of course they have to fit snugly. Tip: Do not overfill the jack with hydraulic fluid. I did, and with enough pressure, the cork burst and a fair amount of liquid from the socket.

I had a Torin Big Red Jack. The instructions say to be careful not to tear the rubber plug when removing it to change the oil. Well I was careful but I ripped it anyway because it was tight and the rubber was old. These fit perfectly. I don't necessarily need twelve of them, but that's how they come. The landing was good and tight. If you're not sure what size hole to plug in because you don't have a metric ruler, 8mm is very close to 5/16 inch.

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.
