Rubber Fuel Filler Neck Hose

Rubber Fuel Filler Hose is a heavy-duty, oil- and fuel-resistant hose designed for transferring petrol, diesel, and other petroleum-based fuels in automotive, marine, and industrial applications. Constructed with a durable NBR (Nitrile Buna Rubber) inner tube, reinforced with a spiral steel wire helix, and protected by a tough CR (Chloroprene Rubber) outer layer, the hose provides outstanding strength, flexibility, and resistance to fuels, oils, and environmental conditions. Built to SAE-30R7 standards, it ensures reliable performance in demanding fuel handling systems. With an operating temperature range of -30°C to +85°C (and peaks up to +100°C), Rubber Fuel Filler Hose delivers long-lasting service in both static and dynamic installations.

Key Features:

• Inner Layer: NBR (Nitrile Buna Rubber) for excellent fuel and oil resistance.

• Reinforcement: Spiral steel wire helix for crush resistance and structural stability.

• Outer Layer: CR (Chloroprene Rubber) for weathering, abrasion, and ozone resistance.

• Operating Temperature: -30°C to +85°C (peak +100°C).

• Working Pressure: 10 bar across available sizes.

• Burst Pressure: 30 bar (3:1 safety factor).

• Internal Diameter Range: 38 mm to 57 mm.

• Wall Thickness: 5 mm to 6 mm depending on size.

• Bending Radius: 200 mm to 280 mm depending on diameter.

• Standard: SAE-30R7 compliant.

The Nitrile rubber inner tube ensures safe compatibility with petrol, diesel, and fuel blends, while the spiral steel helix reinforcement prevents collapse and kinking under suction or bending. The tough Chloroprene outer layer provides resistance to ozone, abrasion, and weathering, extending hose life in harsh working conditions. With a 3:1 safety margin between working and burst pressure, the hose is engineered for reliability and safety in critical fuel handling systems. Its flexibility allows for easy installation in confined engine bays and marine compartments.

Applications include automotive fuel filler necks, marine fuel systems, generator fuel connections, construction machinery, agricultural equipment, and general-purpose fuel transfer. Rubber Fuel Filler Hose is the ideal solution where strength, durability, and resistance to fuels and oils are essential for safe and efficient operation.
