Aluminium Pipes & Fittings
Our Aluminium Pipes & Fittings provide lightweight, easy-to-fabricate components for cold-side intake and intercooler plumbing. Build backbone runs with Aluminium Straight Pipes, handle tight corners with Aluminium 90° Elbow Pipes, and add branches using the Aluminium T-Piece. Enjoy weight savings, clean looks and strong corrosion resistance.
Brief summary & key benefits
Aluminium Pipes & Fittings are the go-to components for cold-side plumbing. They deliver significant weight savings versus stainless, are easy to cut and finish, and look tidy in the bay. The range spans straight tubes, 45°/67°/90°/135°/180° elbows, plus T-pieces—so you can route anything from simple repairs to full charge-pipe systems.
Technical Basics
Aluminium’s high thermal conductivity helps shed heat downstream of the intercooler. Build the backbone with Aluminium Straight Pipes; for compact corners choose Aluminium 90° Elbow Pipes, while Aluminium 67° Elbow Pipes split the difference between 45° and 90°. For larger turns use Aluminium 135° Elbow Pipes or full-return Aluminium 180° U-Bend Pipes. To add branches or recirc lines, fit an Aluminium T-Piece.
Because aluminium is less stiff than steel, avoid excessive clamp torque that might ovalise the tube. Always deburr and clean cuts for step-free joints. These parts are intended for the intake/intercooler side—do not use them on exhaust sections.
Selection Criteria
Diameter: match turbo, intercooler and throttle stubs. Undersizing restricts flow; oversizing lowers air velocity. Angle: choose 45° for smooth turns, 90° for compact corners, 67° as a middle ground, and 135°/180° for major direction changes. Leg length: typical 300/600 mm legs provide trimming allowance for couplers and sensors. Material pairing: if aluminium must meet stainless, isolate with silicone/EPDM to minimise galvanic and thermal-mismatch issues.
Installation & Maintenance
Plan the route, mark cut lines, then cut square, deburr inside and out and degrease. Add a light edge chamfer so silicone couplers slide on cleanly. Align bends to leave enough straight behind each clamp; tighten evenly and re-torque after initial heat cycles. If welding aluminium, use solid fixturing and controlled heat input to manage its higher thermal expansion. Periodically check mounts, shielding and potential chafe points.
FAQ
Can these be used on the exhaust?
No—use stainless there; aluminium is for the cold side.
Which angle should I choose?
45° for gentle routing, 90° for tight packaging, 67° in between, and 135°/180° for big turns.
Clamp or weld?
Cold-side systems typically use silicone couplers and clamps; weld only where fixed geometry is required.
How do I avoid leaks?
Square cuts, thorough deburring, step-free joints and quality clamps—then re-check torque after heat cycles.
