Boyce Industries 3 Inch Oval Mandrel Bend Mild Steel Short Radius 30 45 60 90 Degree

Boyce Industries 3 Inch Oval Mandrel Bend Mild Steel Short Radius 30 45 60 90 Degree

When a round tube won’t clear the tunnel, the frame rail, or the floor pan, an oval mandrel bend gives you the same flow area in a profile that actually fits. Starting from a 3-inch round tube and ovalized on a short-radius die, these Boyce Industries bends hold their cross-section through the entire sweep — no kinks, no collapsed walls — so every weld you put to them goes exactly where the design calls for it.

Key Features

• Bent the “hard way” — flat sides remain on the same plane through the bend for maximum clearance in tight installations
• Mandrel-bent to maintain full oval cross-section with no wall collapse or distortion through the sweep
• CNC-precision short-radius die produces consistent, repeatable geometry ideal for custom exhaust and chassis fabrication
• 16 GA cold rolled mild steel (.065″ wall) is fully weldable with MIG, TIG, or stick processes
• Equal flow area to a 3-inch round tube — no restriction penalty from the oval profile change
• Available in four degree options — 30°, 45°, 60°, and 90° — to suit any routing requirement
• Natural (uncoated) finish accepts paint, coating, or ceramic treatment without surface prep complications
• Proudly made in the U.S.A.

Fitment Notes

• This is a raw fabrication component — no vehicle-specific fitment; suitable for any custom exhaust, header, chassis, or tunnel application requiring a 3″ oval section
• Select the degree that matches your routing geometry — multiple bends can be combined to achieve compound routing angles
• Short-radius bends from the same OSR series will nest inside each other for compact multi-bend routing layouts
• Natural finish — prime, paint, coat, or ceramic-treat after fabrication as required
