Silicone Hose 90 Degree Elbow Pipes - 3 SIZES

These AutoSiliconeHoses 90 Degree Silicone Elbow Hoses provide durable, flexible and heat-resistant connections for automotive, industrial, commercial and general engineering applications. Available in three internal diameter sizes – 32mm, 63mm and 76mm, these reinforced blue silicone bends are suitable for routing compatible air, water and coolant lines where a compact 90-degree connection is required.

Manufactured from a smooth extruded silicone compound with integrated polyester braid reinforcement, these hoses combine flexibility with dimensional stability. The 32mm hose features 3-ply reinforcement and a 4.5mm wall thickness, while the 63mm and 76mm hoses feature 4-ply reinforcement and a 5.5mm wall thickness. This reinforced construction helps control expansion, resist kinking and maintain the hose shape during operation.

Each silicone elbow features a 90-degree bend with 150mm (6") leg lengths, allowing pipework to be routed around engine components, machinery and other obstacles. The smooth internal bore supports efficient airflow and fluid transfer, while the polyester reinforcement provides strength for compatible pressurised applications.

Manufactured to SAE J20 R3, these blue silicone elbow hoses offer resistance to ageing and ozone exposure. The stated temperature range is -50°C to +250°C, with +250°C specified as the peak temperature. Working pressure varies by size, ranging from 3.5 bar to 5.17 bar, with corresponding bursting pressures from 10.5 bar to 15.5 bar and a stated 3:1 safety factor.

Installation Guide

1. Select the Correct Hose Size

Choose the required 32mm, 63mm or 76mm internal diameter according to the outside diameter of your existing pipework or hose connection.

2. Check Installation Clearance

Ensure there is sufficient space for the 90-degree bend and 150mm leg lengths. Check that the hose can be routed without excessive twisting, stretching or contact with sharp edges.

3. Position the Silicone Elbow

Slide each end of the hose over the appropriate pipe or fitting, ensuring that the connections are fully seated and correctly aligned.

4. Secure with Suitable Hose Clamps

Use correctly sized hose clamps suitable for reinforced silicone hose. Tighten them according to the clamp and fitting manufacturer's recommendations.

5. Inspect the Installation

Check that the hose is securely fitted, free from excessive strain and clear of moving components or unsuitable heat sources. Inspect the connections periodically and check for leaks where applicable.

Important Information

These AutoSiliconeHoses 90 Degree Silicone Elbow Hoses are universal components and are not vehicle-specific replacement parts. Compatibility depends on the selected internal diameter, pipe dimensions, operating temperature, working pressure and the type of fluid or air being transferred.

The available options are 32mm, 63mm and 76mm internal diameter only. Please select the correct size before ordering.

Working pressure ratings are size-specific:

• 32mm: 5.17 bar working pressure / 15.5 bar bursting pressure
• 63mm: 4 bar working pressure / 12 bar bursting pressure
• 76mm: 3.5 bar working pressure / 10.5 bar bursting pressure

The stated 3:1 safety factor reflects the relationship between working and bursting pressures. Bursting pressure is not a permissible operating pressure.

The -50°C to +250°C temperature range includes a maximum peak temperature of +250°C. Continuous operation at this maximum temperature should not be assumed without confirmation of the manufacturer's operating limits.

These hoses should only be used with compatible fluids and operating conditions. Suitability for fuel, oil, aggressive chemicals, food contact or other specialist applications must be separately confirmed before installation.
