The curved round wing tip is the ideal technical solution for professionals in the furniture, locksmith and construction industries. Unlike flat models, its curved shape (concave head) fits perfectly with the lines of furniture and offers superior ergonomics. This component is mainly used for sealing and protecting the inside of round metal or plastic tubes.

Why choose a curved profile?

The curved shape is not only aesthetic. It allows you to:

Reduce friction points: Ideal for chair and table legs, limiting scratches on delicate floors.

Secure structures: By moulding to the end of the tube, it eliminates sharp edges and prevents contact injuries.

Optimise sealing: It acts as an airtight shield against the ingress of water, dust or corrosive products, preserving the internal integrity of the tube.

Precision measurement for a perfect fit

To ensure a durable, non-adhesive fit, the dimensions must be carefully selected. It is essential to measure:

● The outer diameter of the tube (its total diameter).
● The wall thickness (the internal void where the fins are inserted).

Thanks to its flexible polyethylene fins, this end cap adapts to manufacturing tolerances, ensuring a firm and permanent tightening. Whether you are working with steel, aluminium or PVC, the curved end cap guarantees a high-quality professional finish.
