Black Fluorine Rubber Fuel Hose & Oil Line Pipe — Precision-Sized ID 1–32mm for Engine, Petrol & Pneumatic Systems
When a leaking or degraded fuel line puts your engine project on hold, the right hose material makes all the difference. This black fluorine rubber tube fuel hose is built for mechanics, small-engine restorers, and DIY enthusiasts who need a reliable, chemical-resistant fuel pipe that holds up under real operating conditions — not just bench tests.
Each length is cut from solid fluorine rubber (FKM/Viton-grade compound) tubing available in inner diameters from 1 mm to 32 mm (~0.04" to 1.26") and outer diameters sized to match. Wall thickness varies by size — typically 1–3 mm depending on the ID/OD combination selected. Lengths are available from 1 meter up to 10 meters per order, letting you buy exactly what the job requires.
Typical applications include engine petrol and diesel fuel lines on motorcycles, small generators, and garden machinery; oil return and breather lines on air-cooled engines; pneumatic pilot lines and low-pressure air circuits; and chemical transfer tubing in workshop or laboratory settings where standard rubber would degrade.
⚠️
Compatibility note: Verify the inner diameter (ID) and outer diameter (OD) against your existing fittings before ordering. This hose is designed for low-to-medium pressure fuel, oil, and pneumatic applications. Not rated for high-pressure hydraulic circuits. Check your engine or equipment manual for maximum operating pressure and temperature requirements.
✅ Key Features of These Fluorine Rubber Fuel Hose Tubes
🧪
Fluorine Rubber (FKM) Construction
Made from fluorocarbon rubber compound with strong resistance to petrol, diesel, engine oil, hydraulic fluid, and many industrial chemicals — significantly more resistant than standard EPDM or silicone hose in fuel service.
📏
Wide Size Range — ID 1 mm to 32 mm
Over 30 ID/OD combinations available, from 1 mm × 3 mm up to 32 mm × 38 mm, covering the majority of small-engine fuel line, oil breather, and pneumatic pilot-line sizes in a single product listing.
✂️
Cut-to-Length Flexibility (1–10 Meters)
Order the exact length you need — 1, 2, 3, 4, 5, or 10 meters — to minimise waste and avoid splicing multiple short sections together on a single run.
🌡️
Heat & Ozone Resistance
Fluorine rubber retains flexibility and sealing integrity across a broad temperature range (typically −20 °C to +200 °C / −4 °F to +392 °F), making it suitable for under-bonnet and engine-bay routing where ambient temperatures are elevated.
⚫
Black Finish — UV & Weathering Stable
The black colouring is consistent throughout the wall, not a surface coating. Carbon-black pigmentation provides additional UV stability for exposed routing on outdoor equipment.
🔧
Barb-Fitting Compatible
The flexible wall allows secure push-fit installation onto standard barbed fittings and hose tails. Clamp with a worm-drive hose clip for a leak-free seal on pressurised circuits.

❓ Frequently Asked Questions
How do I choose the correct ID and OD for my application?
Measure the outer diameter of the barb or hose tail fitting the hose will slide onto — this should match or be very close to the hose's inner diameter (ID) for a secure push-fit. The outer diameter (OD) determines the clearance needed in any routing clips or brackets. If you are replacing an existing hose, measure the old hose's ID and OD directly with calipers.
Is fluorine rubber stronger than standard rubber for fuel lines?
Yes. Fluorine rubber (FKM) has significantly better resistance to petrol, diesel, and aromatic fuels than standard EPDM or nitrile rubber. It also resists swelling and softening when in prolonged contact with modern ethanol-blended fuels (E10, E15), where standard rubber hoses can degrade within months.
Will this hose resist corrosion and weathering outdoors?
Fluorine rubber has good ozone and UV resistance. The black carbon-pigmented compound adds further UV stability. For outdoor equipment such as generators, lawn mowers, or marine applications with exposed hose runs, this material performs better than standard rubber over time. For fully submerged or salt-spray environments, contact us to confirm suitability.
Is this hose compatible with ethanol-blended fuels (E10/E15)?
Fluorine rubber (FKM) is one of the most ethanol-tolerant elastomers available and is widely used in fuel systems where ethanol-blended petrol is the norm. It resists the swelling and hardening that ethanol causes in nitrile and EPDM hoses. Always verify with your equipment manufacturer if your system has specific material approval requirements.
What pressure can this hose handle?
This is an unreinforced flexible tube rated for low-to-medium pressure applications such as gravity-fed or pump-fed fuel lines, oil breather circuits, and pneumatic pilot lines. It is not designed for high-pressure hydraulic circuits. Exact pressure ratings vary by wall thickness and ID/OD combination — contact us with your specific size and application if you need confirmation before ordering.
Do I need a hose clamp, or is push-fit sufficient?
For gravity-fed or very low-pressure lines (e.g., fuel tank to carburettor on small engines), a snug push-fit onto a barbed fitting is often adequate. For any pressurised circuit — including pump-fed fuel systems or pneumatic lines — a worm-drive hose clip or crimp clamp is strongly recommended to prevent blow-off under pressure spikes.
Can I use this hose for pneumatic air lines as well as fuel?
Yes. The smaller ID sizes (1 mm – 10 mm) are well suited to pneumatic pilot lines, instrument air tubing, and low-pressure air circuits in workshop or industrial settings. Fluorine rubber's chemical inertness also makes it suitable for transferring mild acids, solvents, and other chemicals where standard rubber would degrade — verify compatibility with your specific fluid before use.
