Rectangular tube insert 30×70 mm, grey

The grey Rectangular tube insert 30x70 mm is a simple finishing component that closes the open end of a tube and gives the structure a neat, uniform appearance. It is made of polyethylene and sold individually, making it easy to order the exact quantity needed for a project.

The insert has a flat external flange that covers the edge of the tube and an internal section with ribs. The ribs press against the inside of the tube and hold the insert in place. It fits tubes with a wall thickness of 1.5–3.0 mm, so one insert size accommodates several wall thicknesses.

Applications

Polyethylene is a lightweight plastic commonly used for products of this type. The neutral grey colour suits most metal structures.

Selection and installation

Two key parameters determine the choice of insert: the nominal tube size and its wall thickness. Press the insert into the open end of the tube until the flange rests against its edge; the ribs on the internal section hold it in place. The dimensions of the flange, internal section, core and ribs are listed in the specification table, allowing you to check compatibility with the tube before ordering.
