Round tube insert Ø 18 mm, white

The white Round tube insert for Ø 18 mm tubes is a simple finishing component for closing the open ends of round tubes. For installation and assembly companies, it offers a practical way to give profile ends a neat finish in structures, frames and equipment.

The insert consists of a smooth, rounded head and an internal section with ribs. The head covers the edge of the tube and gives the end an even, neat finish, while the ribbed internal section is designed to be pressed into the profile.

Applications and selection

Plastic push-fit inserts are generally used where an open tube end needs to be closed quickly and without additional fixing tools. Tube diameter and wall thickness are important when selecting an insert, as they determine how well the ribs fit. Before installation, check that the tube end is cut evenly and free of burrs, then press the insert in fully until the head sits flush against the edge of the profile.

The product is sold individually, making it easy to order exactly the quantity needed for the job. The white colour complements light-coloured profiles and equipment.

Inserts of this type have an external head and an internal shank with ribs that conform to the inside of the tube when pressed in. This design allows the profile end to be closed without glue or screws and the component to be replaced if necessary.
