Bung Cap 2"Buttress (Coarse Thread) with Gasket for 55 Gallon Plastic Drums -2pc MADE IN USA

Good quality and fits well with a good seal. Great value considering they are hard to find and functions very well.

I bought this cap to help my parents save emergency water in one of their drums outside. They have older drums and some of their caps were no where to be seen. After reading good reviews, this is the first one that I have tried and it works and seals the drum well. I would recommend this product if you are looking for a cap to seal a drum that you have. The pictures show one of the old caps and the newer cap in place in the drum.

We have three 50 gallon water barrels. We've had them for quite a while and the bung caps rotted away. Now I have three water barrels that are useless. I didn't expect to find caps so was thrilled to find these. They fit well and we are back to storing water. It's important to us because we live between the two biggest earthquake faults in Southern California and I don't like being without a water source in case of emergency. So glad to have found these caps.

Worked like it was designed... a threaded bung plug for a plastic barrel. No leaks or drips.

Fits the 55 gallon blue barrels. As always, pay attention, the blue barrels have two bungs, one fine thread and one course thread, usually only one of the stock bungs has a knockout which is why these replacements are so nice, coarse or fine, they all have knockouts.My buddy works for an RV place, they get RV antifreeze in these blue barrels. You can flush these barrels with water and they are safe for water storage.

Functions as designed, fast shipping.

Good product fits perfectly try wouldnuy again

In broad overview, I did make this work. However, the problem was the "knock out" for the ¾ inch pipe thread. It doesn't knock out - at least not without destroying the product. I had to drill it out - using a metal ¾ inch "nipple" to protect the plastic threads while I used a ¾ inch spade drill bit to drill out the "knock out". Also, the ¾ inch pipe threads are very soft and easily destroyed (which is why I protected them with a metal nipple to do the drilling). It is easy to strip out these threads. I ruined two bungs until I found this technique for getting the "knock outs" out.So, the theory of these bungs is good. The execution is not good. If I were going to buy more I would look for some other product made with more durable plastic, and true "knock out" for the pipe fitting.Addendum: they leak. At least in the drums I have, the gasket used on these bungs leak. The gasket is thin and sits up inside of the flange for the bung (other products use a better silicone ring that is thicker and butts up against the flange). In my experience these bungs leaked when used in a configuration where the barrels (used as rain barrels) were laid on their side. I intentionally laid the barrels on their side, rather than upright, to keep the pressure in the outflow pipes low.Anyway, these bungs are cheap and if you don't need much they might work for you. For me they have not worked.

Real size 2 1/2 " or 63.5mmThe size isn't right, it is bigger, I can't screw on the blue plastic drum.
