Silicone Radiator Hose is a durable, heat-resistant straight hose designed for efficient coolant transfer in automotive, industrial, and marine applications. Manufactured with high-grade silicone inner and outer layers reinforced by strong polyester braid, this hose delivers excellent pressure stability, flexibility, and resistance to ageing. Built to SAE J20 R3 standards, it ensures reliable performance in high-temperature environments, operating continuously between -50°C and +220°C, withstanding peaks of up to +250°C. Its multi-ply wall construction offers both strength and flexibility, while the smooth bore design ensures efficient coolant and fluid flow. Supplied in convenient 1-metre lengths and a wide range of diameters, silicone radiator hose provides long-lasting service in engine bays, heavy machinery, and custom-builds where durability and heat resistance are critical.

Key Features:

Material (Inner & Outer): High-grade silicone for heat and ageing resistance.

Reinforcement: Polyester braid for stability and strength under pressure.

Construction: 3–4 ply with smooth bore for efficient coolant flow.

Operating Temperature: -50°C to +220°C (peak +250°C).

Internal Diameter Range: 6 mm to 152 mm.

Working Pressure: Up to 8.3 bar (small bore) down to 1.5 bar (large bore).

Bursting Pressure: Typically 3x working pressure (up to 27 bar).

Length Supplied: 1 metre straight sections.

Standard: SAE J20 R3 compliant.

The silicone radiator hose combines multiple layers of reinforced polyester braid with resilient silicone, providing excellent flexibility and pressure tolerance. Its ability to withstand extreme temperatures makes it especially suited to engine coolant transfer, industrial thermal management, and marine cooling systems. The thick multi-ply wall construction provides stability against pressure cycling, while the silicone exterior resists ozone, UV, and environmental degradation for extended service life. With smooth internal walls that minimise turbulence and pressure loss, the hose ensures efficient coolant circulation and dependable system performance. Burst pressures up to three times the working rating deliver a robust safety margin for critical operations, while 1-metre supply lengths support easy installation and replacement in custom setups.

Applications include automotive radiators, intercooler and turbo coolant routing, marine cooling systems, agricultural engines, motorsport builds, and industrial equipment requiring resilient coolant transfer. Silicone radiator hose is widely used in maintenance, upgrades, and high-performance engineering projects where conventional rubber hoses are prone to failure.
