42.0mm Black Round Domed Tube Insert - To Fit 37.0-39.0mm | LDPE

Commonly used across gym and fitness equipment, this black round tube insert combines a ribbed push-fit shank with a domed top. The supplied 42.0mm outside diameter, 1.5-2.5mm wall range and 37.0-39.0mm tube compatibility make sizing straightforward before installation. Its profile combines a 21.0mm head height with a 30.0mm insert section.

What Are Round Domed Tube Inserts?

Round tube end inserts provide both finishing and protection for open tubular sections. The LDPE body flexes during installation so the external ribs can grip the inside wall while the domed top forms the visible finished end of the tube.

Common Applications

  • Furniture Manufacture: Finishes exposed round chair, table and shelving tubes with a smooth protective end.
  • Industrial Fabrication: Closes open round sections on fabricated frames and equipment structures.
  • Office Furniture: Finishes tubular desk, seating and storage components used in commercial interiors.
  • Machinery Protection: Helps stop dirt and debris entering open tubular sections on suitable equipment.
