The Exhaust Tube Bend Long Leg is a stainless steel mandrel-bent tube fitting produced specifically for exhaust system fabrication and high-flow tube routing applications, available in three bend angles: 45°, 90°, and 180°, all sharing the defining long-leg configuration visible in the image. As shown, the fitting features a generous straight tangent section extending from each end of the bend arc, providing substantial straight tube length on both legs that simplifies alignment, clamping, and welding into an exhaust or tube system during fabrication and installation.
Supplied with a 1.6mm wall in an unpolished surface condition and manufactured from Grade 304 stainless steel, these bends are produced by mandrel bending, a process where a precision internal mandrel supports the tube wall throughout the bend, preserving a consistent, round cross-section and wrinkle-free bore along the full length of the arc. This maintains the full bore area through the bend, minimising back pressure and flow restriction, critical performance requirements in exhaust and high-velocity fluid systems.
The 45° bend is available in 38.1mm, 44.45mm, 57mm, 76.2mm, and 88.9mm. The 90° bend, the most commonly specified angle for exhaust routing, covers 38.1mm, 44.45mm, 57mm, 63.5mm, and 76.2mm. The 180° bend, used for full-direction reversals in compact exhaust circuits, is available in 44.45mm and 57mm. The unpolished surface condition is standard for exhaust and underbody tube applications where surface finish is not a primary requirement. Grade 304 stainless steel provides excellent resistance to the high temperatures, condensate, and oxidising conditions inherent in exhaust service, ensuring long-term durability and corrosion resistance throughout the service life of the exhaust system.
