Nitrile Rubber Fuel Hose — Flexible Oil & Petrol Line for Engines, Machinery & DIY Repairs

When a cracked or hardened fuel line causes leaks on a small engine, motorcycle, generator, or garden machine, finding the right replacement hose in the exact bore size is the first obstacle. This nitrile rubber fuel tube is stocked in 22 inner-diameter options — from 2 mm (0.08 in) up to 25 mm (0.98 in) — so mechanics, smallholders, and hands-on DIYers can match the original line without adapters or compromise.

Each length is cut from smooth-bore nitrile rubber (NBR) tubing with an inner diameter ranging from 2 mm to 25 mm and an outer diameter from 4 mm to 31 mm. Wall thickness varies by size. The tube is black, flexible, and rated for continuous use between −20 °C and 80 °C (−4 °F to 176 °F). Available in 1 M, 2 M, 3 M, 5 M, and 10 M cut lengths to suit single repairs or workshop stock.

Typical applications include replacing petrol and diesel feed lines on lawnmowers, chainsaws, and outboard motors; routing hydraulic fluid or oil return lines on compact machinery; and building custom fuel systems where a flexible nitrile rubber hose for petrol, diesel, and oil is required. The smooth bore minimises flow restriction, making it suitable as a low-pressure fuel transfer hose or vacuum line on small engines.

⚠️ Compatibility note: This hose is designed for low-pressure fuel, oil, and diesel applications. It is not rated for high-pressure hydraulic systems or brake fluid. Always verify the inner diameter and wall thickness against your existing line before ordering.

✅ Key Features of These Nitrile Rubber Fuel Hose Tubes

🔩 22 bore sizes in one listing — inner diameters from 2 mm to 25 mm (0.08–0.98 in) and outer diameters from 4 mm to 31 mm, covering the most common small-engine and machinery fuel line sizes.
🛢️ Nitrile rubber (NBR) construction — resists petrol, diesel, mineral oil, and hydraulic fluid without swelling or cracking, maintaining a secure seal over repeated heat cycles.
🌡️ Wide temperature range — rated −20 °C to 80 °C (−4 °F to 176 °F), suitable for outdoor engines exposed to cold starts and sustained running temperatures.
📏 Five cut lengths available — choose 1 M, 2 M, 3 M, 5 M, or 10 M to match a single repair job or to keep a workshop roll on hand for multiple jobs.
🔄 Smooth bore, flexible wall — the smooth internal surface reduces turbulence in low-pressure fuel flow; the flexible wall allows routing around tight bends without kinking.
✂️ Cut-to-length convenience — supplied as a continuous length so you can trim to the exact measurement needed, reducing waste and avoiding unnecessary joins in the fuel line.

❓ Frequently Asked Questions

How do I choose the right inner diameter for my fuel line?

Measure the outside diameter of the fitting or barb the hose will connect to — this should match the inner diameter (ID) of the tube for a snug push-fit seal. If you have the old hose, measure its ID directly with calipers. When in doubt, size down rather than up: a slightly tight fit seals better than a loose one on a barbed connector.

Is this hose suitable for diesel as well as petrol?

Yes. Nitrile rubber (NBR) is resistant to both petrol (gasoline) and diesel fuel, as well as mineral oils and hydraulic fluids. It is not recommended for use with brake fluid (DOT), strong solvents, or aromatic fuels above typical pump concentrations.

What is the maximum operating temperature?

This tube is rated for continuous use between −20 °C and 80 °C (−4 °F to 176 °F). It is suitable for most small engine and machinery fuel line applications. Avoid routing the hose directly against exhaust components or other surfaces that exceed 80 °C.

Can I use this hose for high-pressure hydraulic systems?

No. This is a low-pressure fuel and oil line hose. It is not rated for high-pressure hydraulic circuits. For high-pressure applications, a reinforced hydraulic hose with a rated working pressure is required. If you are unsure of your system's pressure, contact us before ordering.

How do I cut the hose to length cleanly?

Use a sharp utility knife or hose cutter on a flat surface. Score around the circumference first, then cut through in one firm motion. Avoid sawing back and forth, which can leave a ragged edge that reduces seal quality. A clean, square cut ensures the hose seats fully against the barb or fitting.

Which size should I order if I need to replace a hose on a lawnmower or chainsaw?

Most small garden engines use fuel lines with an inner diameter of 2 mm to 5 mm. The 3×5 mm and 3×6 mm sizes are the most common replacements for chainsaws and string trimmers, while lawnmowers often use 5×8 mm or 6×9 mm. Check your machine's service manual or measure the existing hose to confirm before ordering.

Does the hose require hose clamps or jubilee clips?

For low-pressure gravity-fed or suction fuel lines, a push-fit onto a barbed connector is often sufficient. For any pressurised line or where vibration is present, fitting a worm-drive hose clamp (jubilee clip) over the hose end is recommended to prevent the hose from working loose over time.
