Silicone Coupling Hose is a high-quality reinforced straight connector designed for joining pipework and tubing across automotive, marine, and industrial systems. Manufactured from premium silicone with polyester braid reinforcement, the hose provides excellent pressure resistance, flexibility, and long service life. With a temperature range from -50°C to +220°C (and peaks up to +250°C), it is engineered to perform in extreme under-bonnet and industrial environments. The smooth bore ensures efficient airflow or fluid transfer, while the multi-ply wall construction maintains dimensional stability under vibration, heat, and pressure cycling. Available in diameters from 13 mm up to 152 mm, the silicone coupling hose is suitable for both performance upgrades and heavy-duty applications.

Key Features:

• Material: Silicone inner and outer layers for resilience and heat resistance.

• Reinforcement: Polyester braid for pressure stability and durability.

• Construction: 3–4 ply reinforced straight hose with smooth bore.

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

• Internal Diameter Range: 13 mm to 152 mm.

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

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

• Length Supplied: Various lengths depending on specification.

• Standard: SAE J20 R3 compliant.

The reinforced silicone coupling hose offers a strong combination of durability and flexibility, making it ideal for coolant, turbo, and induction systems. Its polyester braid reinforcement provides stability under pressure, while the silicone outer layer protects against heat, ozone, and environmental degradation. The multi-ply structure ensures a secure and reliable connection even in high-performance or heavy-duty conditions. With burst ratings up to three times the working pressure, the hose provides an excellent safety margin, supporting long-term use in continuous service environments.

Applications include automotive coolant and induction pipework, turbocharger and intercooler couplings, marine cooling systems, motorsport builds, agricultural equipment, and industrial fluid transfer. Widely used for performance upgrades, preventative maintenance, and custom fabrication, silicone coupling hoses deliver dependable performance where standard rubber hoses fall short.
