Description
Round tube insert Ø 25 mm, anthracite

The Round tube insert for Ø 25 mm tube in anthracite (RAL 7016) provides a neat finish for open tube ends. It covers the tube opening and gives the structure a finished appearance.
The insert is pressed into the end of the tube. The ribbed internal section fits against the tube wall and holds the insert in place, while the wider external head covers the tube edge. Installation simply involves pressing the insert into the tube opening.
Practical applications
- finishing the ends of round tubes in support structures, frames and racks
- covering open tube ends in metal components
- creating a consistent appearance thanks to the neutral anthracite colour
- sold individually – making it easy to select the required quantity for each project

Choosing the right insert for the tube
Before purchasing, check the tube diameter and wall thickness. The insert has a nominal size of 25 mm and is designed for round tubes of this diameter. The ribs on the internal section allow it to fit tubes with different wall thicknesses. A correctly sized insert sits securely, with its head flush against the end of the tube.
