ALUMINIUM BENDS
Aluminium bends and straight tube for building custom intake, exhaust and plumbing runs. This range covers mandrel bends in various angles and diameters, straight tube lengths, and aluminium donuts used to join pieces together.
The bends come in 30°, 45°, 90° and 180° angles across diameters from 2" up to 4", so you can pick the angle and size that matches the run you're building. Straight tube is available in different diameters and wall thicknesses for sections that don't need to turn. Aluminium donuts are flat rings used to weld tube sections together where a bend meets a straight run or another bend.
Choose your diameter first to match the rest of your system, then pick the angle of bend needed for the path the tube has to take. There's also fuel safety foam in this category for fitting inside fuel cells or tanks.
Frequently asked questions
How do I choose the right bend angle?
Pick the angle that matches the direction change needed in your tube run, with 30°, 45°, 90° and 180° options available to suit tighter or wider turns.
What's the difference between straight tube and mandrel bends?
Straight tube is used for runs that don't change direction, while mandrel bends are pre-formed to a set angle so the tube keeps a consistent internal diameter through the bend rather than collapsing.
What are the aluminium donuts used for?
They're flat aluminium rings welded between tube sections, commonly used to join a bend to a straight piece or to connect two bends together.
Does wall thickness matter when choosing tube?
Yes, thicker wall tube will be heavier and more robust, while thinner wall tube saves weight, so match it to how much strength the application needs.
