Ribbed plugs for round tubes

Characteristics and design of the plugs

Our plugs are made of high-quality polyethylene (PE), a material known for its UV, deformation, and weather resistance. Their unique design, with smoothly rounded contours and a matte surface, ensures a perfect fit into round tubes.

Protective and safety functions

Round tube plugs are not just visually appealing — they play a key role by covering sharp edges, preventing injuries, and blocking moisture or contaminants from entering the tube.

Simple attachment and wide-ranging uses

Installing these plastic plugs is extremely easy. Integrated ribs ensure a secure hold without adhesive. Ideal for metal or plastic constructions, railings, playground equipment, and much more.
