135° Aluminium Elbow is a precision-formed alloy bend designed for secure, lightweight, and corrosion-resistant pipework connections. Manufactured from high-grade T6063 aluminium, the elbow offers excellent durability and strength while keeping weight to a minimum, making it ideal for automotive, marine, agricultural, and industrial applications. The smooth bore provides efficient flow with minimal turbulence, while the polished finish ensures a clean and professional appearance. With a 135° bend and equal 100 mm leg lengths, the elbow is designed for reliable integration into a wide variety of hose and pipework systems.

Key Features:

Material: T6063 aluminium alloy for strength, corrosion resistance, and lightweight performance.
Construction: Precision-formed 135° elbow with smooth bore and polished finish.
Bend Angle: 135° for wide-angle redirection in pipework and hose systems.
Leg Lengths: Standard 100 mm legs for secure coupling.
Wall Thickness: 1.6 mm across all sizes.
Outside Diameter Range: Available from 13 mm up to 102 mm.
Operating Temperature: -40°C to +220°C (peak +240°C).
Compatibility: Suitable for use with reinforced silicone or rubber hoses, secured with clamps.
Applications: Turbocharger and intercooler pipework, coolant plumbing, air intake routing, marine cooling circuits, and general industrial fluid transfer.

Made from T6063 aluminium, the elbow balances durability with reduced weight, making it particularly suited to motorsport and high-performance systems. The 135° bend provides an effective solution for routing pipework around awkward or wide angles, reducing the need for multiple connectors. With smooth internal walls, the elbow minimises flow resistance and pressure drop, while its polished surface resists oxidation and enhances appearance. Easy to install with clamps, the aluminium elbow offers a professional and reliable solution for custom fabrication and system upgrades.

Applications include intercooler and turbocharger systems, automotive cooling and induction layouts, marine engine cooling, agricultural machinery, and industrial pipework. 135° Aluminium Elbows are widely used in engineering, motorsport, and performance projects requiring lightweight, strong, and corrosion-resistant angled pipework.

How to measure OD

Measure across the outside

Rigid pipe, tube and joiners are sized by the outer wall, because that is the surface a hose seals against. The bore and wall thickness follow from it — they are not the ordering size.

Use vernier calipers

Set the outer jaws across the widest point. A tape measure round a curve reads low by a millimetre or two — enough to buy the wrong size.

Take three readings, keep the largest

Rotate 60° between each. If they disagree the tube is oval; size to the biggest figure so the hose still clamps down evenly.

Match the hose to this OD

The hose sleeves over the tube, so the hose you want is the one whose internal diameter equals this outside diameter. A 51 mm tube takes a 51 mm ID hose.

Order by OD, always. Tube, rigid pipe and joiners are listed by outside diameter — the surface the hose clamps onto. Pair one with a hose of the same ID. On reducers, quote both ends, largest first.

Frequently Asked Questions.

Answers to the questions we’re asked most about sizing, fitment and performance.

Still can't find your answer?

What is it used for?

Changing the direction of a hard pipework run - intake, boost, coolant and industrial pipework - without using a flexible hose. A metal elbow holds its shape under pressure and keeps the bore round for flow.

What size do I order?

Order by outside diameter, because that is what your hose or coupler slides over - match it to the internal diameter of the silicone or rubber hose you are using. Measure with vernier callipers rather than a tape. Available in outside diameters from 13mm to 102mm.

What material and rating is it?

T6063 aluminium alloy with a 1.6mm wall, rated -40C to +220C. T6063 gives good strength and corrosion resistance at low weight, sheds heat well, and will not rust like mild steel.

What leg lengths does it have?

100mm on each side, giving 200mm total length. Trim from the plain section if you need it shorter, leaving at least 25-30mm of straight leg beyond the bend for the hose and clamp to seat on, and deburr inside and out so the edge cannot score the hose bore.

Are the ends beaded, and does it matter?

Yes - each end is formed with a bead, so the clamp pulls the hose down behind a raised lip rather than relying on friction alone. That is what stops a joint blowing off under boost, and it is why beaded parts are the right choice for charge air pipework.

Aluminium or stainless - which should I choose?

Aluminium is lighter, cheaper and rejects heat faster, which makes it the usual choice for intercooler and intake pipework. Stainless is stronger, far better in salt environments and takes a superior polish, so it suits marine work and visible show pipework. Both are rated -40C to +220C and can be mixed in one system.
