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

Ideal for storage systems and racking, this 18.0mm round tube end insert closes open tube ends with a smooth domed profile. The grey LDPE insert is designed for 1.0-2.0mm wall thickness and 14.0-16.0mm tubing, including a 8.0mm domed head and 12.0mm insertion depth.

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

  • Machinery Protection: Helps stop dirt and debris entering open tubular sections on suitable equipment.
  • General Maintenance: Replaces missing or damaged push-fit inserts on compatible round tube.
  • Retail Displays: Creates a neat end detail on stands, racks and shopfitting frameworks.
  • Railings: Covers open round tube ends on compatible internal or external railing assemblies.
