Round tube insert Ø 40 mm, black

The black Round tube insert Ø 40 mm is a finishing component that closes the open end of a tube and gives the structure a neat, uniform appearance. It is sold individually, making it easy to order the exact number required for your project.

The inner section of the insert has ribs that hold it in place when pressed into the tube. The flat outer flange covers the edge of the tube and conceals its cross-section. The insert is designed for tubes with a nominal diameter of 40 mm and a wall thickness of 1.5–2.5 mm, making it suitable for standard round tubes of this size.

Application and selection

Round tube inserts are used to close the open ends of tubular profiles, improving the appearance of the finished structure and protecting the cut edge. Before ordering, check the tube diameter and wall thickness — inserts of this type are selected according to the nominal profile size. The black colour complements dark profiles and structural components.

Installation

Press the insert into the open end of the tube until the outer flange rests against the tube edge. The ribs flex during insertion and hold the component securely in the tube. Before installation, ensure that the tube edge is clean and free of burrs.
