U-Bend Mild Steel 2.500 x 6in Radius 18 Gauge

The HOOKER U-Bend Mild Steel 2.500 x 6in Radius 18 Gauge exhaust component is engineered for marine engine builders and boat technicians who demand precision-bent tubing for custom exhaust systems. Whether you're restoring a classic inboard engine, building a high-performance marine power plant, or fabricating replacement exhaust runs, this mandrel-bent U-bend delivers the smooth flow characteristics critical to optimal engine performance on the water. Built from mild steel and precision-mandrel bent to a consistent 6-inch radius, this component eliminates the turbulence and flow restrictions that occur with poorly formed bends.

The 2.5-inch diameter tubing with 18-gauge wall thickness provides the ideal balance of structural integrity and weight savings for marine exhaust applications. The mandrel-bent construction maintains consistent wall thickness throughout the bend radius, preventing the collapse or thinning that reduces exhaust scavenging efficiency and increases backpressure. With 12-inch legs and a 6-inch bend radius, this U-bend integrates seamlessly into exhaust manifold-to-transom runs on inline and V-block engines, accommodating typical marine engine compartment dimensions while minimizing installation complexity.

Marine engine enthusiasts and professional boatyard technicians rely on HOOKER's U-Bend Mild Steel 2.500 x 6in Radius 18 Gauge for both new fabrication and direct replacement applications. Its mild steel construction is weldable without special procedures, allowing for custom fitting during exhaust system assembly. This component is sold individually, making it ideal for single-run fabrication or point repair on existing marine exhaust systems. Proper installation requires alignment with intake manifold discharge ports and transom exits to ensure full flow potential and reliable long-term marine service.
