This sheet metal cutout is a rotationally symmetric component made of aluminium, featuring an external thread of 140 mm diameter and an internal thread of 90 mm diameter.
It typically serves as an adapter, transition piece, or mounting element for connecting two parts with different thread sizes.
Aluminium provides good corrosion resistance, low weight, and is suitable for various industrial applications, including tank construction, vehicle manufacturing, and process engineering.
Depending on the version, the part may be milled, turned, or deep-drawn before threading.
