Square Domed Tube Inserts are designed to provide a secure and professional finish to square tubes, pipes, and box sections. Manufactured from high-quality LDPE plastic (Low-Density Polyethylene), these inserts offer a durable and long-lasting push-fit solution, ensuring a firm grip and a neat, aesthetic appearance.

The domed head design enhances the visual appeal of furniture and tubular structures while serving a functional role in protecting against moisture, dust, and debris ingress. These inserts help to prevent internal corrosion and contamination, extending the lifespan of tubes and reducing maintenance costs.

Square Domed Inserts are commonly used in furniture manufacturing, industrial applications, and structural tubing, where a clean, capped-off finish is required. Their ribbed shank design ensures they remain firmly in place, accommodating a range of wall thicknesses for a secure fit without adhesives or fixings.

How to Choose the Correct Size

To ensure a proper fit, selecting the correct size of Square Domed Tube Inserts is essential. Follow these steps:

• Measure the outside dimensions (width and height) of your square tube or box section.
• Determine the wall thickness of the tube.
• Subtract the wall thickness from the outside dimensions to find the correct ‘To Fit Tube' size.

We stock these inserts in a range of sizes from 16mm to 24mm to accommodate various applications. If you need help selecting the right size, our expert team is available to assist. Business customers can also request a free sample to test the fit before making a bulk purchase.
