Silicone 45° Elbow Hose is a high-performance connector designed for coolant, air, and fluid transfer in automotive, marine, and industrial applications. Constructed with a smooth extruded silicone compound inner layer, reinforced by strong polyester braids, and finished with a durable silicone outer layer, this hose delivers excellent flexibility, pressure stability, and heat resistance. The 45-degree bend with 150 mm legs allows efficient routing in compact or angled systems, reducing the need for additional fittings. Built to SAE J20 R3 standards, this multi-ply hose operates reliably from -50°C to +250°C, making it suitable for demanding environments where conventional hoses may degrade. Available in diameters ranging from 6.5 mm to 102 mm, the silicone elbow ensures versatile compatibility across multiple fluid handling systems.

Key Features:

• Inner Layer: Smooth extruded silicone compound for durability and flexibility.

• Reinforcement: Polyester braids for pressure resistance and dimensional stability.

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

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

• 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: Typically 3x working pressure (up to 37 bar).

• Bend Angle: 45° with 150 mm leg lengths for reliable installation.

• Standard: SAE J20 R3 compliant.

The silicone elbow’s reinforced multi-ply structure provides reliable pressure handling and durability in both low- and high-temperature environments. Its smooth bore supports efficient coolant and air transfer with minimal flow resistance, while the silicone exterior resists cracking, ozone, and long-term environmental exposure. Polyester braid reinforcement maintains structural integrity and pressure stability, making the hose suitable for use in systems subject to vibration and thermal cycling. With working pressures up to 12.33 bar in smaller diameters and burst ratings up to 37 bar, the hose offers a strong safety margin across a wide range of applications. The angled design reduces the need for multiple connectors, simplifying system layout and improving flow efficiency.

Applications include automotive coolant and air systems, turbocharger and intercooler connections, marine cooling circuits, motorsport performance builds, agricultural engines, and industrial machinery requiring durable angled connections. Silicone 45° elbow hoses are also widely used in custom fabrication, heavy-duty maintenance, and high-performance upgrades.
