12mm Round Ribbed Tube Insert, 1-1.5mm

These 12mm round ribbed tube inserts are designed to provide a clean, secure finish for hollow round tubes and pipes. Thanks to the flexible lateral ribs running around the shank of the insert, they should be suitable for tube wall thickness of between 1 to 2mm metric (14-20 gauge imperial), unless otherwise stated. 

Manufactured from durable LDPE plastic, they are commonly used as protective end caps, tube feet, and finishing plugs across furniture, fabrication, and light industrial applications. They're designed to retain themselves inside tube, with the head sitting over the outer ends of the tube or pipe, sitting flush with the outside circumference of the tube and providing a neat finished appearance.

Key Features:

• Fits hollow tube or pipe with a 12mm outer dimension
• Manufactured from resilient LDPE
• Ribbed design for secure fitting
• Helps protect floors from exposed tube ends, reducing noise and marking
• Available in multiple colours
• Designed primarily for indoor use but can be used outside but not UV stabilised as standard

Technical Information:

• Tube or pipe shape: Round
• External tube size: Ø12mm
• Tube wall thickness: 1–1.5mm
• Suggested internal fit: 9-10mm approx. (different factors affect this, including coatings, weld lines and tolerance)
• Material: Low-Density Polyethylene (LDPE)
• Fitting type: Push-fit ribbed insert

Suitable for:

• Office and workshop furniture
• Chairs and tables
• Round hollow tubes and pipes
• Display systems
• Gates and railings
• Light fabrication projects
• Protective tube end finishing
• POS and Shopfitting

Tube inserts are always listed the same way that tube is listed because the head of the insert needs to marry up with the outside edges of the tube.  They often come in a variety of wall thicknesses and gauge sizes but if you're unsure on fit, you can click the 'Request Sample' button, or for help measuring your tube, try out this useful sizing pdf.

If this isn't quite right for your application, check out our domed, angled, chrome and metal inserts and if you're not looking to plug the end of a piece of hollow tube and instead after a generic hole plug, then maybe one of our covers caps or panel plugs will work better for you.

Frequently asked questions about this item are shown below. Do you have a question? Submit FAQ

Q: Once the insert is placed fully into the end of a tube, what are the dimensions of the exposed part of the insert?

A: Looking at the Blue 'View Drawing' button that is on that product page, it shows the 'H' Dimension which is the head thickness as 4mm - so that's the thickness of the material that will protrude over the outside edge of the tube but as with the vast majority of our products, there's an Orange 'Request Sample' button on the product page you can click, to get one sent to you for appraisal foc.
