These aluminium half donuts are designed to be welded together to create custom bends and directional changes in aluminium piping. They are commonly used in intercooler and intake fabrication where tight-radius or non-standard bends are required. Key Features • Weld-together half donut design for custom bend fabrication • Ideal for intercooler and intake piping • Allows tight-radius and custom-angle bends • Suitable for TIG welding • Commonly used in custom and performance fabrication Specifications • Material: Aluminium • Application: Intercooler and intake piping • Use: Weld together to form bends or transitions • Supplied as individual half donuts Often used alongside aluminium straight tube, silicone hose joiners, and intercooler clamps in custom intake and intercooler systems.
