Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

Engineered from high-quality Low-Density Polyethylene (LDPE), this square plastic cap is designed for durability and resilience in industrial environments. The material offers excellent resistance to impact, moisture, and UV degradation, ensuring a long service life for both indoor and outdoor applications. Its ribbed design creates a secure friction fit inside the tubing, preventing it from dislodging due to vibration or environmental changes. This makes it a reliable component for finishing a wide range of metal fabrication projects.

These 1/2 inch square plastic caps are essential MRO supplies for fabricators, manufacturers, and maintenance teams in Los Angeles. They are commonly used to cap the ends of metal fencing, furniture, equipment frames, and machinery guards to improve safety and aesthetics. By sealing the tube ends, they also prevent the ingress of dirt, moisture, and insects, protecting the structural integrity of the tubing from the inside out. They provide a cost-effective and professional finish for both new fabrications and repairs.

Specifications

  • Material: Low-Density Polyethylene (LDPE)
  • Standards: Industrial Manufacturing Standard
  • Strength/Tensile: High-Impact Resistance
  • Dimensions: Fits 1/2" x 1/2" Square Tubing (Outer Dimension)
  • Finish: Matte Black

Applications

  • Fabrication & Welding: Finishing protective guards, frames, and custom metalwork.
  • Fencing & Railing: Capping posts and rails to prevent water ingress and improve safety.
  • Equipment Manufacturing: Providing a clean finish on machinery legs, handles, and frames.
  • MRO & Repair: Replacing worn or missing end caps on existing structures and equipment.

Target Users

Ideal for metal fabricators, maintenance professionals, furniture makers, and fencing contractors in the Los Angeles area who require a durable finishing component for square tubing projects.

Finish Options

Our 1/2 inch square plastic caps are stocked in a standard matte black finish, which provides a professional look and UV resistance. Other colors may be available for bulk orders upon request.

How to Measure

To ensure a proper fit, measure the outer dimension (OD) of your square tube. This cap is designed to fit a tube with a 1/2 inch x 1/2 inch outside measurement. The cap's internal ribs will accommodate minor variations in tube wall thickness.

Example: For a 1/2" OD square tube, specify '1/2 Inch Square Plastic Cap'.
