They fit and seal well as expected.

Cap is exactly as expected, but slightly small for my application. It does fit and I can get it to snug down, but I can tell the correct size should be maybe 1/8 inch larger. Can't blame the manufacturer, though -- I just assumed they were all interchangeable.

The item was exactly what I needed. I had a water barrel that was missing the plug. Tank Barn delivered it in a timely manner and for a reasonable price.

We rotate our emergency water every 6 months, so we have only had to take this off/on a couple of times. Works as expected.

These are definitely the course threads, not fine thread! Very fast delivery! Works perfectly and I like that these have the center knock out for a hose or siphon pump!

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