45° Aluminium Elbow is a precision-formed alloy bend designed for use in automotive, marine, agricultural, and industrial systems where lightweight, corrosion-resistant pipework is required. Manufactured from high-grade T6063 aluminium, the elbow combines strength and durability with reduced weight compared to steel alternatives. Its smooth bore ensures efficient airflow or fluid transfer with minimal turbulence, while the polished finish provides both protection and a professional appearance. Designed to integrate seamlessly with silicone or rubber hoses, the elbow delivers a secure and long-lasting connection when installed with standard clamps.

Key Features:

Material: T6063 aluminium alloy for strength, corrosion resistance, and lightweight performance.
Construction: Precision-formed 45° bend with smooth bore for efficient flow.
Bend Angle: 45° for angled connections in hose and pipework systems.
Lengths Available: Typically supplied in 150 mm leg lengths for secure coupling.
Operating Temperature: -40°C to +220°C (peak +240°C).
Compatibility: Designed for use with reinforced silicone and rubber hoses secured by clamps.
Applications: Turbocharger and intercooler pipework, coolant and induction systems, marine cooling circuits, and industrial fluid handling.
Finish: Polished aluminium surface for professional appearance and added durability.

Constructed from T6063 aluminium, the elbow offers excellent corrosion resistance and strength while remaining lightweight for performance-critical applications. The 45° bend provides a simple solution for redirecting pipework without the need for multiple joints, reducing turbulence and improving system efficiency. The smooth internal bore supports unrestricted airflow or coolant circulation, while the polished outer surface protects against oxidation and ensures a clean, professional look. Easy to install with clamps, the aluminium elbow integrates reliably with silicone hose systems for both custom builds and maintenance work.

Applications include intercooler and turbocharger systems, coolant and air intake routing in automotive engines, marine cooling layouts, agricultural equipment, and industrial machinery. 45° Aluminium Elbows are widely used in motorsport, custom fabrication, and engineering projects where strong, lightweight, and corrosion-resistant angled pipework is required.

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?

150mm on each side, giving 300mm 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.
