Rubber 90 Degree Elbow is a durable and heat-resistant connector hose designed for coolant, air, and water transfer in automotive, agricultural, and industrial systems. Manufactured from smooth EPDM rubber and reinforced with high-tensile fibre yarn, the elbow offers excellent pressure stability, flexibility, and long service life. Its moulded 90-degree bend provides reliable directional change in confined spaces while maintaining consistent flow. Built to SAEJ20R3 standards, the hose resists heat, ozone, and weathering, ensuring performance in demanding environments. With an operating temperature range of -30°C to +125°C (and peak resistance up to +145°C), Rubber 90 Degree Elbow is suitable for a wide range of fluid handling applications where reliability and strength are essential.

Key Features:

Material: Smooth heat-resistant EPDM rubber for flexibility and durability.
Reinforcement: High-tensile fibre yarn for dimensional stability and pressure strength.
Design: Precision-moulded 90-degree elbow for secure angled connections.
Operating Temperature: -30°C to +125°C (short-term peak +145°C).
Working Pressure: 10 bar across all sizes.
Burst Pressure: 30 bar (3:1 safety factor).
Internal Diameter Range: 9.5 mm to 76 mm.
Wall Thickness: 4.5 mm across all sizes.
Leg Length: 150 mm per leg.
Standard: SAEJ20R3 compliant.

The EPDM construction provides strong resistance to heat, weathering, and ozone, extending the hose’s lifespan in tough working conditions. Its reinforced design ensures stability under pressure, while the smooth bore supports efficient coolant and air flow. The moulded 90-degree shape helps prevent kinking in confined installations, making it highly effective for routing hoses around engine bays, machinery, and equipment. With a burst rating three times higher than its working pressure, the elbow delivers a secure and reliable solution in critical fluid transfer systems.

Applications include automotive coolant and heating systems, agricultural machinery, construction equipment, marine engines, and general industrial water or air handling. Rubber 90 Degree Elbow provides a dependable and versatile solution wherever durable, heat-resistant, and flexible hose connections are required.

How to measure ID

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.

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.

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.

Round to the nearest listed bore

Never go up: a bore wider than the fitting will not grip, whatever the hose is made of. If you land between listed sizes take the smaller bore, and secure it with a clip.

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.

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 for?

Turning a corner in a coolant, air or water run without kinking. A moulded elbow keeps the bore round through the bend, so flow is not restricted and the hose will not collapse - which is what happens if you bend a straight hose round the same corner.

What size do I order?

Order by internal diameter, matched to the outside diameter of the pipe stub the elbow slides onto. Measure the pipe with vernier callipers rather than the old hose. Available in internal diameters from 10mm to 76mm.

How long are the legs?

150mm on each side, giving 300mm total length. Trim with a sharp blade, leaving at least 25-30mm of straight leg beyond the bend so the clip seats on a supported section. Never let a clip end up on the curve of the bend.

What is it rated for?

EPDM rubber built to SAE J20 R3 with high-tensile fibre yarn reinforcement, glycol rated for standard antifreeze mixes. That is the specification used for virtually all original-equipment coolant hose.

Can I use it for fuel or oil?

No - EPDM has poor resistance to hydrocarbons and will soften and swell. For fuel and oil use our SAE J30 R6 rubber hose or a fluorosilicone-lined silicone elbow.

Rubber or silicone elbow?

Rubber is the like-for-like replacement, cheaper, and matches the original look on a standard vehicle. Silicone handles far higher temperatures and does not perish with age, so it is the better choice if the vehicle runs hot or access is poor enough that you do not want to do the job again.
