U-Bend Mild Steel 3.000 x 6in Radius 18 Gauge

The HEDMAN U-Bend Mild Steel 3.000 x 6in Radius 18 Gauge mandrel bend is engineered for builders and mechanics who demand precision-formed exhaust tubing without compromise. This 3-inch diameter U-bend represents the gold standard in custom exhaust fabrication, allowing you to route piping around engine blocks, frame rails, and tight underbody spaces without restrictive kinks or crimping. Whether you're building a performance street rod, fabricating a custom truck exhaust, or designing a competition engine bay, this mandrel-bent component eliminates the flow losses that plague inferior crush bends.

Constructed from mild steel and finished in natural (unpainted) state, the HEDMAN mandrel bend features a 6-inch radius that maintains consistent wall thickness throughout the bend—critical for exhaust scavenging and backpressure control. The 18-gauge steel thickness provides durability for street and race applications while remaining workable for TIG welding or slip-fit connections. The 6.5-inch legs deliver ample material for coupling to flanges, collector outlets, or downpipe sections, and the precise mandrel-forming process ensures no material thinning or deformation at the bend centerline that would otherwise create turbulence and efficiency loss.

Professional fabricators, restoration shops, and serious DIY builders rely on HEDMAN mandrel bends for custom primary pipe routing, turbo downpipes, and secondary exhaust paths where OEM bends don't fit the application. The natural finish allows you to ceramic coat, powder coat, or polish the component to match your build aesthetic. At 5.65 lbs, this U-bend is manageable for single-operator installation while providing the structural integrity required for high-heat exhaust environments. Welding-grade mild steel accepts standard automotive welding techniques without special preparation.
