Our Aluminium 180° U-bend pipes are lightweight bends for intake and intercooler plumbing. Offered in popular diameters (e.g., 51–70 mm; some items 2"–2.75") with a typical 600 mm leg, they provide ample trimming allowance. Aluminium cuts weight and resists corrosion, helping you build compact, tidy routes on the cold side.

Brief summary & key benefits
Aluminium 180° U-bend pipes create a full U-turn on the cold side with a single component—handy when space is tight and the charge pipe must reverse direction. With aluminium construction they keep weight down and reduce loads on brackets and clamps. Typical options cover 51–70 mm (some items 2"–2.75") and around 600 mm legs, giving generous trimming freedom.
Technical Basics
A 180° bend links two straight runs with a large direction change, often reducing joint count compared with multiple smaller elbows. On the cold side, aluminium offers good corrosion resistance and a smooth internal surface for airflow. Check actual outside diameters and tolerances so silicone couplers and clamps seat without steps or leaks.
Selection Criteria
Diameter: match turbo, intercooler and throttle-body stubs; undersizing restricts, oversizing can lower air velocity. Leg length: a typical 600 mm leg leaves room for trimming and for sensors or joiners. Wall gauge: light gauges suit most cold-side builds; choose heavier walls for long unsupported spans or harsh duty. Material strategy: keep aluminium throughout a section to minimise galvanic effects and thermal mismatch.
Installation & Maintenance
Mark cut lines, then deburr and degrease. Add a light edge chamfer to protect silicone. Tighten clamps evenly—excess torque can ovalise the tube. If welding, allow for aluminium’s higher thermal expansion and conductivity; use solid fixturing and controlled heat input. Pressure- or smoke-test for leaks and re-torque clamps after initial heat cycles. Inspect brackets and potential chafe points periodically.
FAQ
Can I use these on the exhaust?
No—use stainless steel for hot sections; aluminium U-bends are for intake/intercooler plumbing.
What sizes are available?
Commonly 51–70 mm with some 2"–2.75" options.
What leg length do they have?
Typically around 600 mm for flexible fitment.
Clamp or weld?
Cold-side systems are usually silicone + clamps; weld only when fixed geometry is needed.
Why is my joint leaking?
Usually burrs, angled cuts or undersized/low-quality clamps. Re-cut square, deburr and retighten.
