20.0mm Black Round Domed Tube Insert - To Fit 16.0-18.0mm | 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 20.0mm outside diameter, 0.8-2.0mm wall range and 16.0-18.0mm tube compatibility make sizing straightforward before installation. Its profile combines a 9.5mm head height with a 15.5mm insert section.

What Are Round Domed Tube Inserts?

A round domed insert is a simple end-finishing fitting for tubular products. The LDPE construction provides enough flexibility for the ribbed body to compress during installation then grip inside the compatible tube while the head remains visible as a smooth protective cap.

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.
