45° Stainless Steel Elbow is a precision-formed connector designed for use in demanding automotive, marine, agricultural, and industrial systems. Manufactured from high-grade stainless steel, the elbow provides exceptional strength, corrosion resistance, and long service life even in harsh environments. Its 45° bend allows pipework to be routed efficiently around tight spaces while maintaining smooth fluid or airflow. The polished stainless finish delivers both durability and a professional appearance, making it ideal for performance, heavy-duty, and custom applications. Designed to work in conjunction with reinforced silicone or rubber hoses, the elbow ensures a secure and reliable connection when fitted with standard clamps.

Key Features:

Material: High-grade stainless steel for superior strength and corrosion resistance.
Construction: Precision-formed 45° elbow with smooth bore for efficient flow.
Bend Angle: 45° for angled routing in hose and pipework systems.
Lengths Available: Typically supplied with 150 mm leg lengths for secure coupling.
Operating Temperature: Suitable for high- and low-temperature service across -50°C to +250°C.
Durability: Resistant to heat, vibration, and chemical exposure in harsh operating conditions.
Applications: Turbocharger and intercooler pipework, coolant and air induction systems, marine cooling, and industrial fluid transfer.
Finish: Polished stainless steel surface for strength, durability, and professional appearance.

Constructed from stainless steel, the elbow offers unrivalled durability compared to aluminium alternatives, making it especially suited to harsh environments where exposure to heat, chemicals, or salt water is a concern. The 45° bend provides efficient redirection of pipework, reducing the need for additional joints and improving system flow. Its smooth internal bore ensures minimal turbulence, while the polished external finish protects against corrosion and enhances appearance. Easy to integrate with reinforced silicone hoses and clamps, stainless steel elbows provide a strong, leak-free connection built to withstand high stress and pressure.

Applications include intercooler and turbocharger systems, coolant pipework, agricultural engines, marine cooling circuits, and industrial fluid handling systems. 45° Stainless Steel Elbows are widely used in motorsport, heavy-duty vehicles, and engineering projects where maximum durability and corrosion resistance are required.

How to measure OD

1

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.

2

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.

3

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.

4

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?

Contact Us

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?

304 stainless steel, polished, rated -40C to +220C. 304 is the standard corrosion-resistant grade - it resists rust, coolant and road salt without any coating.

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?

These have plain precision-machined ends. That makes them easy to slide hose onto and lets you set the hose position exactly, which suits coolant and low-pressure runs. For pressurised charge air, choose a beaded joiner instead.

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.
