The purpose of the present invention is to provide a hose cap that eliminates the above-mentioned drawbacks, and is characterized by forming an iron-zinc film on the outer circumferential surface of the hose cap made of carbon steel. In addition, a fluorine-based resin was applied to the coating on the sleeve portion of the cap.

In this case, by attaching a zinc-iron film with good heat resistance (OK up to 300℃) instead of galvanizing, we aim to increase heat resistance and corrosion resistance, and prevent cracks in the film during caulking or wringing. A highly elongated fluorine-based resin (100% or more) is applied to prevent corrosion resistance from deteriorating.
