PPE 45-Degree Aluminum Mandrel Bend Tube 4.0" OD, 12-Gauge (Universal)

This is a PPE 45-degree mandrel-bent aluminum tube, 4.0" OD with a 6.0" centerline radius and a 12-gauge (0.080") wall. Mandrel bending keeps the large tube from crushing, so the diameter stays consistent and high-volume airflow stays smooth.

The 45-degree bend makes gentle transitions in a large charge-air or intake run, and the 0.080" aluminum wall keeps the piece light while handling boost pressure.

It is a building block for fabricated intake, intercooler, and turbo plumbing on the big 4.0" size, common on higher-output builds that move a lot of air.

This is raw mandrel-bent tube for fabrication, so plan to cut it to length and weld it into your system. Confirm 4.0" OD suits your couplers and clamps before ordering.
