18.0mm White Round Domed Tube Insert - To Fit 14.0-16.0mm | LDPE

Manufactured to finish and protect round tubing in commercial furniture and shelving, this white domed round tube insert has a 18.0mm outside diameter and suits the uploaded 14.0-16.0mm tube size range. Its LDPE construction provides a resilient tube-end barrier while the 1.0-2.0mm wall compatibility helps ensure the correct internal grip. The visible dome is 8.0mm high and the insert section is 12.0mm long.

What Are Round Domed Tube Inserts?

Round domed tube inserts are push-fit components used to close the open ends of round tubing. Their ribbed shank grips inside the tube while the rounded head remains visible above the end, creating a smoother finish and helping prevent dirt, moisture and debris from entering the section.

Common Applications

  • Railings: Covers open round tube ends on compatible internal or external railing assemblies.
  • Storage Systems: Protects exposed tube ends on racks, frames and light storage structures.
  • Display Furniture: Adds a rounded finished end to tubular exhibition and presentation structures.
  • Furniture Manufacture: Finishes exposed round chair, table and shelving tubes with a smooth protective end.
