Silicone 45° Reducing Elbow is a high-performance connector designed to join pipes of different diameters while providing a smooth 45-degree bend for efficient routing. Manufactured with a smooth extruded silicone compound inner layer, reinforced by strong polyester braids, and finished with a high-quality silicone outer layer, this hose delivers excellent flexibility, durability, and resistance to heat and pressure. The reducing elbow design enables transitions between different bore sizes without compromising flow, making it ideal for cooling, air, and fluid systems. Built to SAE J20 R3 standards, this multi-ply hose operates reliably between -50°C and +250°C, ensuring dependable service across a wide range of demanding automotive, marine, and industrial applications.

Key Features:

• Inner Layer: Smooth extruded silicone compound for efficient fluid and air transfer.

• Reinforcement: Polyester braids for stability and pressure resistance.

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

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

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

• Internal Diameter Range: 6.5 mm to 127 mm.

• Working Pressure: From 12.33 bar (small bore) down to 1.9 bar (large bore).

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

• Bend Angle: 45° with reducing bore transition.

• Standard: SAE J20 R3 compliant.

The silicone reducing elbow is designed to handle both size transitions and angled routing in confined or complex system layouts. Its multi-ply polyester reinforcement provides excellent strength and dimensional stability, while the silicone layers resist thermal degradation, cracking, and ozone damage. With working pressures up to 12.33 bar for smaller bores and burst ratings up to three times higher, the elbow ensures a strong safety margin across diverse applications. The smooth bore design minimises turbulence, supporting efficient fluid and air transfer, while the reinforced wall construction offers durability under vibration and thermal cycling. This makes the hose an excellent solution for installations requiring both reduction and angled connections.

Applications include automotive coolant and intercooler systems, turbocharger pipework, air intake connections, marine cooling lines, agricultural engines, and industrial fluid transfer where bore transitions are required. Widely used in performance upgrades, custom fabrication, and heavy-duty maintenance, silicone 45° reducing elbows provide durability, reliability, and flexible installation.
