Round tube insert Ø 12 mm, grey

The grey Round tube insert for Ø 12 mm tubes is a finishing component for closing the open ends of round tubes. Inserts of this type protect the inside of the tube from dirt and give the end of the profile a neat, closed appearance.

Push-fit design with ribs – the internal section with retaining ribs fits inside the tube and is held in place by friction, while the flat, rounded external flange covers the edge of the profile. One size fits tubes with different wall thicknesses, making selection easier when ordering for several types of tube with the same nominal diameter.

Application and selection – Round tube inserts are commonly used to finish tube ends in structures, frames, supports and equipment. The correct insert is selected according to the nominal tube diameter and wall thickness – detailed dimensions are provided in the specification tables below.

Dimensional drawing – the letter designations used in the specification correspond to the insert dimensions: external height (C), internal height (H) and profile wall thickness (R). This makes it easier to check the insert against the tube before ordering.
