Oval tube insert 20×40 mm, black

The black Oval tube insert 20×40 mm is a finishing component that closes the open end of a tube and gives the structure a neat, attractive appearance. It is made of polyethylene and sold individually in units of 1 piece.

Applications and selection

The insert consists of a flat external section that covers the edge of the tube and an internal section that slides inside it. The fins on the internal section press against the tube walls, holding the insert in place once pushed into the opening. This is a typical design for push-in inserts for closed-section tubes.

Installation and use

Push the insert into the end of the tube until the external section rests against its edge. Before installation, check that the end of the tube is free of burrs and matches the nominal dimensions of 20×40 mm.

Material

Polyethylene is a material commonly used to manufacture tube inserts and feet. Its flexibility allows the fins to conform to the inside of the tube and hold the insert in place. It is lightweight, so the component adds little weight to the structure it finishes.

Dimension designations

The insert dimensions are described using standard designations: the external section, the internal section with its core, and the fins that determine the fit against the tube wall. Specific values are listed in the specification tables below.
