Since thread in the area of ​​household water channels and, indeed, Waterbarrels connections are often equipped with fine thread, but our rain collector has a hose connection thread of 1 inch, adjusted our various (now I know it yes) PVC closure caps not; neither of the Thread still the height ago.
... And then it went to the fruitless search until I "was the code word" cap "or cap)

Since I had decided already in rain barrels through for brass, and the cap of the same material should be. Well, et voilà, here it is, in great quality and, for a small-volume buyers like me, in a very fair price / performance ratio.

Note .:
Meanwhile, I have found the caps in PVC under the search words:
