When space is tight and precision matters, our tight radius aluminium donut halves are the go-to solution for high-end intercooler and intake fabrication. Designed for professional fabricators and serious car builders, these donut halves allow you to create ultra-compact bends without sacrificing airflow or fitment.
Engineered for Tight Spaces
Featuring a 0.75D bend radius, these donut halves make it possible to route piping where standard mandrel bends simply won’t fit. Perfect for modern engine bays, turbo setups, and custom intake layouts where every millimetre counts.
Manufactured from 5052 aluminium spun from 2mm sheet, they offer excellent strength, corrosion resistance, and outstanding weldability. The precision spinning process ensures clean edges and accurate geometry, resulting in no gaps during fit-up—saving you time during fabrication and delivering cleaner welds.
