Silicone 90° Elbow Hose is a high-performance connector designed for efficient fluid, air, and coolant transfer in automotive, marine, and industrial systems. Constructed with a smooth extruded silicone compound inner layer, reinforced with strong polyester braids, and finished with a durable silicone outer surface, the hose delivers excellent flexibility, strength, and long-term reliability. The 90-degree bend with 150 mm legs on each side provides a secure fit and helps streamline installation in compact or angled system layouts. Built to SAE J20 R3 standards, this reinforced multi-ply elbow operates reliably across temperatures from -50°C to +250°C, withstanding demanding environments such as engine bays, intercooler connections, and industrial equipment. Available in internal diameters from 6.5 mm up to 102 mm, the elbow hose covers a wide range of performance and heavy-duty applications.

Key Features:

  • Inner Layer: Smooth extruded silicone compound for strength and flow efficiency.

  • Reinforcement: Polyester braids providing pressure stability and flexibility.

  • Outer Layer: High-quality silicone offering resistance to ozone, heat, and abrasion.

  • Construction: 3–4 ply with 150 mm leg lengths for secure installation.

  • Operating Temperature: -50°C to +250°C (peak +250°C).

  • Internal Diameter Range: 6.5 mm to 102 mm.

  • Working Pressure: From 12.33 bar (small bore) down to 2.8 bar (large bore).

  • Bursting Pressure: Up to 37 bar (typically 3x working pressure).

  • Bend Angle: 90° with 150 mm legs for compact installations.

  • Standard: SAE J20 R3 compliant.

The polyester-reinforced construction gives the hose a strong combination of flexibility and structural stability, ensuring it maintains integrity under vibration, thermal cycling, and continuous pressure. The silicone exterior resists cracking, ozone, and environmental wear, while the smooth bore design reduces turbulence and supports efficient fluid transfer. With working pressures from 12.33 bar down to 2.8 bar depending on diameter, and burst ratings up to 37 bar, the elbow offers robust safety margins. Its angled design reduces the need for additional couplers, simplifying routing while maintaining efficient flow in performance and industrial systems. This makes it an excellent choice where reliability, heat resistance, and secure connections are essential.

Applications include automotive coolant and air systems, turbocharger and intercooler pipework, marine cooling circuits, industrial thermal management, motorsport builds, and agricultural machinery. Silicone 90° elbow hoses are widely used in high-performance upgrades, maintenance, and heavy-duty engineering projects requiring durable angled connections.

How to measure ID

ID OD wall reinforcement plies ID = bore · OD = ID + (2 × wall)
1
Measure the pipe, not the old hose
Heat and age make a used hose swell and go out of round. Take your reading across the metal outlet the hose slides onto — that measurement is your ID.
2
Use vernier calipers
Set the outer jaws across the widest point of the pipe. 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 pipe is oval; size to the biggest figure so the hose still seals.
4
Round to the nearest listed bore
Silicone stretches slightly. If you land between sizes, go down to the smaller bore for a tight seal — never up.
Order by ID, always. Every hose on this site is listed by internal diameter. OD is given for clearance only — it changes with wall thickness and ply count, so it is never the ordering size. On reducers, quote both ends, largest first.

What size do I order?
Order by internal diameter, matched to the outside diameter of the metal pipe or stub the elbow slides onto. Measure the pipe itself with vernier callipers, not the hose you are replacing - hose stretches in service and reads a size large. Available in internal diameters from 6mm to 102mm, in black, blue and red.

How long are the legs?
150mm on each side, giving 300mm total length. That leaves plenty of material to trim back to the length you need. If you cut them down, leave at least 25-30mm of straight leg beyond the bend so the clip seats on a supported section - never let a clip end up sitting on the curve, because it will not seal evenly there.

What temperature and pressure will it take?
Continuous service from -50C to +250C, built to SAE J20 R3. Working pressure runs from 12.33 bar on the smallest bore down to 2.8 bar on the largest, with burst pressure from 37 bar down to 8.5 bar across the 6.5mm to 102mm range. For context, a car cooling system typically runs at 1 to 1.5 bar and well under 120C, so there is a substantial margin.

How is it constructed, and how many plies?
A smooth extruded silicone compound inner layer, polyester braid reinforcement, and a durable silicone outer layer that resists heat, ozone and abrasion. Smaller bores are 3 ply and larger bores step up to 4 ply - each size is built with the reinforcement it needs, so you do not have to specify it. Wall thickness runs from 4.5mm to 5.5mm depending on bore.

Can I use it for fuel or oil?
No. This is standard silicone, which is excellent with coolant, water and air but swells and breaks down in contact with petrol, diesel or oil - and that includes breather and catch-can lines, which carry oil mist. For anything with hydrocarbons in it, use our Fuel & Oil range, which has a fluorosilicone liner built to SAE J30 R6.

What is the bend radius?
Bend radius runs from 16mm on the smallest bore to 70mm on the largest. That is the radius the elbow is moulded to, so the bore stays fully round through the bend and flow is not restricted - which is exactly why a moulded elbow beats bending a straight hose round the same corner.
