They are specifically designed for round pipes and are made of UV-stable PVC, allowing them to be used both indoors and outdoors. Thanks to their conical design, they allow for flexible adaptation to different pipe diameters within a specific range.

In practical testing, the PVC caps from Plasticmetall performed well in all relevant areas. The fit was very good: the caps could be installed without excessive force and sat securely and without play afterward. During the shake test, they remained firmly fixed to the pipe end.
The compression test demonstrated high material stability—even under strong manual pressure, no cracks or permanent deformations occurred. Even after a 24-hour cold test, the structure and fit remained unchanged.
Repeated removal and reattachment showed no significant signs of wear. The caps retained their shape and function completely.
Cleaning was straightforward. Dirt could be removed without any problems.
Overall, the field test confirmedvery robust, durable, and reliable product quality.
