Description

Fluorosilicone Coupling Hose is a reinforced straight connector designed for high-performance applications where resistance to fuels, oils, and hydrocarbon vapours is essential. Constructed with a fluorosilicone inner lining, polyester braid reinforcement, and a durable silicone outer layer, this coupling hose provides excellent chemical resistance combined with strength and flexibility. Built to SAE J20 R6 standards, it operates across a wide temperature range of -50°C to +250°C, making it suitable for both high-heat and chemically aggressive environments. Supplied in various lengths and available in diameters from 6 mm to 63 mm, fluorosilicone couplings deliver reliable long-term performance in both automotive and industrial systems.

Key Features:

  • Inner Layer: Fluorosilicone compound for resistance to fuels, oils, and hydrocarbon vapours.

  • Reinforcement: Polyester braid for pressure stability and durability.

  • Outer Layer: High-grade silicone for thermal, ozone, and abrasion resistance.

  • Construction: 3–4 ply reinforced wall with smooth bore for efficient flow.

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

  • Internal Diameter Range: 6 mm to 63 mm.

  • Working Pressure: From 10 bar (small bore) down to 4 bar (large bore).

  • Bursting Pressure: Typically 3x working pressure (up to 30 bar).

  • Length Supplied: Various lengths depending on specification.

  • Standard: SAE J20 R6 compliant.

The fluorosilicone inner lining provides superior chemical compatibility compared to standard silicone, ensuring reliable service in systems exposed to fuels, oils, and aggressive vapours. Polyester braid reinforcement stabilises the hose under working pressure, while the thick multi-ply wall delivers long service life under vibration and thermal cycling. With burst ratings up to three times the working limit, the hose offers a robust safety margin across multiple industries. The smooth bore construction ensures efficient fluid or air transfer with minimal turbulence, while the outer silicone layer enhances protection against abrasion and environmental wear.

Applications include automotive fuel and oil systems, turbocharger and intercooler connections, marine fuel transfer lines, industrial lubrication and hydrocarbon handling, and agricultural machinery. Fluorosilicone coupling hoses are widely used in motorsport, heavy-duty maintenance, and custom fabrication projects where both chemical resistance and heat tolerance are critical.
