Plastic Caps

Plastic End Caps for Square, Round & Rectangular Tube
Browse our extensive range of premium plastic end caps designed to provide a neat, professional finish while protecting the ends of aluminium, steel, and stainless steel tubing. Available in a wide variety of sizes and shapes, our plastic end caps are suitable for square, round, and rectangular tube applications across residential, commercial, and industrial projects.
Plastic end caps are ideal for sealing open tube ends, preventing dirt, dust, moisture, and insects from entering while reducing sharp edges and protecting floors and surfaces from damage. They are widely used in aluminium handrails, fencing, furniture, gates, pergolas, signage, fabrication, engineering, and general manufacturing.
Manufactured from durable, high-quality plastic, our push-in tube caps are easy to install and provide a secure, long-lasting fit. Whether you're replacing worn caps or completing a new project, you'll find the right size to suit your application.
We proudly supply quality plastic end caps with competitive pricing, fast Australia-wide shipping, and a growing range of tube inserts and finishing components for professionals, tradespeople, manufacturers, and DIY enthusiasts.
