Square Plastic End Caps: Friction Fit Tube Seals for Square Tubing

The Square Plastic End Caps are a simple yet essential accessory designed to seal the open ends of square steel tubing. These caps offer a clean, finished look while protecting the inside of the tubing from moisture, debris, and corrosion. Designed for a secure friction fit, they easily tap into place by hand or with a rubber mallet, making installation quick and tool-free. For more permanent applications, a suitable adhesive can be used to enhance retention.

Made from durable, weather-resistant plastic, these end caps are built for both indoor and outdoor environments and will not rust, crack, or degrade over time. Available in a dark gray color, they complement the industrial aesthetic of galvanized square tubing. Compatible with 25 mm or 40 mm square tubing with a 2 mm wall thickness, they are ideal for finishing pipe-based furniture, railings, safety barriers, and storage racks.
