Nitrile Rubber Fuel Hose — Reliable Petrol, Diesel & Oil Line Tubing for Automotive & Small Engine Repairs

When a cracked or hardened fuel line leaves your mower, motorcycle, generator, or classic car sidelined, you need a replacement hose that seals reliably and resists swelling from day one. This nitrile rubber fuel hose is built for DIYers, mechanics, and small engine technicians who need a dependable, cut-to-length solution without overpaying for pre-formed assemblies.

Each length is a single continuous piece of smooth bore nitrile rubber (NBR) tubing, available in seven inner diameter sizes — 5mm (≈3/16"), 6mm (≈1/4"), 8mm (≈5/16"), 10mm (≈3/8"), 13mm (≈1/2"), 16mm (≈5/8"), and 19mm (≈3/4") — paired with lengths from 1M (≈3.3 ft) up to 10M (≈32.8 ft). The smooth interior bore minimizes flow restriction, and the flexible wall allows routing around tight bends without kinking.

Typical applications include low-pressure petrol feed lines on lawn mowers and garden equipment, diesel return lines on small generators and marine engines, oil drain and crankcase breather hoses on motorcycles and ATVs, and general-purpose fluid transfer lines in workshop and industrial settings where a flexible nitrile rubber oil hose is required.

ℹ️ Compatibility note: This hose is designed for low-pressure, gravity-fed, or return-line fuel systems. It is not rated for high-pressure fuel injection. Confirm your system pressure and fluid type before installation. Not recommended for ethanol blends above E20.

✅ Key Features of These Nitrile Rubber Fuel Hose Tubes

⛽Fuel & Oil Resistant NBR Material — Nitrile rubber resists swelling and degradation when in contact with petrol, diesel, and mineral oils, making it a dependable choice for automotive fuel line replacement.
📏Seven ID Sizes, Six Lengths — Available from 5×8mm up to 19×25mm (ID×OD), with lengths from 1M to 10M, so you can match your exact fitting size and cut only what you need.
🔄Smooth Bore Interior — The smooth inner wall reduces turbulence and flow restriction compared to corrugated alternatives, keeping fuel delivery consistent in gravity-fed and low-pressure systems.
🔧Flexible & Easy to Route — The nitrile rubber wall flexes around bends and corners without kinking, simplifying installation in tight engine bays, under decks, or along frame rails.
✂️Cut-to-Length Convenience — Sold in straight lengths up to 10M (≈32.8 ft), this hose cuts cleanly with a utility knife — no special tools required — so you get exactly the run you need with minimal waste.
🌡️Broad Temperature Tolerance — Nitrile rubber generally maintains flexibility and sealing integrity across a wide temperature range, typically suitable for continuous use up to around 100°C (212°F) in engine bay environments.

❓ Frequently Asked Questions

How do I choose the right hose size?

Match the ID (inner diameter) to your fitting or barb size. For example, a 5mm ID hose fits a 5mm barb fitting. The OD determines how much clearance you need in tight spaces. If you're unsure, measure your existing hose or fitting with calipers — typically the ID is the critical dimension for flow and sealing. As a quick reference: 5mm ≈ 3/16", 6mm ≈ 1/4", 8mm ≈ 5/16", 10mm ≈ 3/8", 13mm ≈ 1/2", 16mm ≈ 5/8", 19mm ≈ 3/4".

Is this hose compatible with petrol and diesel fuel?

Yes. Nitrile rubber (NBR) is generally resistant to petroleum-based fuels including petrol, diesel, and mineral oils. It is not recommended for use with ethanol blends above E20 or aggressive solvents without confirming compatibility. For E85 or flex-fuel applications, a fluorocarbon (FKM/Viton) hose is typically required.

What pressure can this fuel hose handle?

This is a low-pressure smooth bore hose suitable for gravity-fed or low-pressure fuel systems, typically up to around 0.3–0.5 MPa (43–72 psi) depending on size and temperature. It is not designed for high-pressure fuel injection lines. If your application requires higher pressure, contact us to confirm suitability before ordering.

Can I use this hose outdoors or in an engine bay?

Nitrile rubber generally handles engine bay temperatures well, typically rated for continuous use up to around 100°C (212°F). It has moderate UV resistance but is not ideal for prolonged direct sunlight exposure without shielding. For outdoor installations, consider wrapping exposed sections with heat-resistant sleeving or conduit.

What fittings are compatible with this hose?

This hose is designed for push-on or hose-clamp style barb fittings. Select a barb fitting whose barb OD matches the hose ID for a secure seal. Standard metric barb fittings are compatible. Always use a hose clamp for fuel applications — do not rely on friction fit alone in pressurized or vibrating environments.

Can I cut this hose to a custom length?

Yes. The hose is sold in straight lengths (1M, 2M, 3M, 5M, 8M, 10M) and can be cut cleanly with a sharp utility knife or hose cutter. The smooth bore interior makes cutting straightforward without fraying. Select the next length up from what you need to allow for trimming and fitting.

Is this hose suitable for oil return lines and crankcase breathers?

Yes. NBR nitrile rubber is commonly used for oil return, oil drain, and crankcase breather lines in automotive and small engine applications. It is generally compatible with mineral-based engine oils and gear oils. Confirm the operating temperature and pressure are within the hose's rated range before installation.
