G005-01-01-Plastic Square Tube Insert
English Name: Plastic Square Tube Insert / Multi-Rib Square Tube End Cap
Material: Plastic
Product Description:
This is a plastic insert specifically designed to be fitted into the open ends of square metal or plastic tubes. Its shape is precisely matched to the tube’s inner diameter, and it features multiple strengthening ribs to ensure a secure, tight fit once inserted. Made from reinforced, heavy-duty plastic, it provides excellent durability and abrasion resistance.
Product Features:
Dimensions: Designed for 16mm x 16mm square tubes. The actual size of the insert is slightly smaller than the tube’s outer diameter, relying on the flexibility of the ribs to create a snug and secure fit.
Multi-Rib Structure: The sides of the insert have multiple parallel elastic ribs. When pressed into the tube, these ribs compress to create friction, ensuring a tight, stable, and hard-to-remove fit. This design also makes installation easy.
Heavy End Walls: The exposed end of the insert features a thickened wall design. This heavy-duty construction provides superior durability and resistance to impact and daily wear, extending the product’s lifespan.
Plastic Material: Made from plastic, which is lightweight, corrosion-resistant, and an electrical insulator. Different plastic grades can offer varying degrees of hardness, elasticity, and chemical resistance.
Functional Design: The top is usually flat or slightly raised, allowing it to serve as a furniture glide. It provides a non-slip surface, protects floors from scratches, and reduces noise when furniture is moved.
Product Functions:
Sealing and Protection: Closes off the end of the square tube, preventing dust, moisture, insects, or other debris from entering, and protecting the tube’s interior and structure.
Aesthetic Finish: Provides a clean, professional-looking end that hides rough-cut edges.
Furniture Glide: Acts as a foot cap for chairs, tables, and other furniture, protecting floors from scratches, reducing noise during movement, and providing some slip resistance.
Durability and Abrasion Resistance: The heavy-duty, thick-walled design makes it especially suitable for applications that are subject to high pressure, frequent friction, or harsh environments.
Usage Suggestions:
Size Selection: Choose an insert size that precisely matches the inner diameter of your square tube.
Installation: Simply press the insert directly into the tube opening until the ribs are fully seated for a secure fit.
Compatibility: Suitable for end protection on various square steel tubes, aluminum alloy tubes, and plastic tubes.
Application Areas:
Furniture manufacturing (chair and table legs, racks, display stands, etc.)
