Description
Rectangular tube insert 40×120 mm, white, wall thickness 1.7–3.0 mm

The white Rectangular tube insert 40×120 mm is a finishing component for closing the open ends of hollow sections. It is made of polyethylene, a material commonly used for inserts because it is lightweight and resistant to moisture.
Inserts of this type have a flange that sits against the edge of the tube and a push-in internal section with ribs that adapt to the inside of the tube. The wall thickness range covers several tube variants with the same nominal dimensions, so one insert fits different variants.
Applications and selection
- Protecting the ends of steel and aluminium tubes against dirt and moisture ingress.
- Finishing structures, frames, supports and equipment where the open end of a tube is visible.
- Selection according to the nominal tube dimensions and wall thickness.

The white colour suits light-coloured structures and equipment where the insert needs to blend in. The core and rib dimensions in the specification make it easier to compare the insert with the inside of the tube before ordering.

When selecting an insert for a hollow section, first check the tube's external dimensions and wall thickness. Both values must match to ensure that the insert sits snugly against the edge of the tube once pushed in.
