Round tube insert Ø 70 mm, black

The black Round tube insert Ø 70 mm provides a neat finish for an open tube end. It is pressed into the tube, with the flat outer flange sitting against the end and covering the tube edge.

The inner section is fitted with fins that adapt to the tube wall and hold the insert in place. This makes the insert suitable for tubes with different wall thicknesses within the range specified.

Applications and selection

Internal inserts of this type are used to close the ends of round tubes wherever a clean, neat finish is required. The black plastic complements dark profiles and structures, while the smooth, flat top gives the end an attractive finish.

When selecting an insert, two tube parameters are essential: outer diameter and wall thickness. The fins engage with the inside of the tube, so the wall thickness determines how securely the insert fits.

Construction

The insert consists of an outer section, comprising a flange that sits against the end of the tube, and an inner section with a core and fins that enter the tube. The flange limits the insertion depth, while the fins press against the inner tube wall.

The full dimensions of the individual components, including the heights of the outer and inner sections and the dimensions of the core and fins, are given in the specification below.
