NBR Nitrile Rubber Fuel Hose — Flexible Oil & Petrol Line Tubing for DIY Automotive & Machinery

Chasing a fuel leak under the hood or replacing a cracked oil line on aging equipment? Degraded rubber hoses are one of the most common causes of fuel system failures for home mechanics, small engine owners, and industrial maintenance crews. This 5-meter NBR nitrile rubber fuel hose gives you a reliable, cut-to-length solution without the markup of pre-cut OEM replacements.

Each roll contains 5 meters (≈16.4 ft) of flexible nitrile butadiene rubber (NBR) tubing. Available in inner diameters from 3mm (≈1/8") to 25mm (≈1") with matching outer diameters from 6mm to 31mm, the wall thickness varies by size to maintain structural integrity across the range. The black rubber construction is resistant to petroleum-based fluids and remains flexible across a broad temperature range typical of engine bay environments.

Typical use cases include DIY automotive fuel line replacement on cars, motorcycles, and ATVs; oil return and breather lines on small engines and generators; low-pressure hydraulic hose runs on farm equipment and workshop machinery; and coolant or fluid transfer lines in industrial maintenance settings where a flexible nitrile rubber hose is specified.

🔗 Compatibility Note: This hose is designed for use with standard barb fittings and hose clamps. Match the hose inner diameter (ID) to your fitting's barb OD for a secure seal. Not rated for high-pressure hydraulic circuits or brake fluid systems.

✅ Key Features of These NBR Nitrile Rubber Fuel Hoses

⛽Oil & Fuel Resistant NBR Compound — Nitrile butadiene rubber is specifically formulated to resist swelling and degradation from petrol, diesel, motor oil, and hydraulic fluid, keeping your fuel line replacement reliable long-term.
📏Wide Size Range in One Listing — Inner diameters from 3mm (≈1/8") to 25mm (≈1") cover the most common automotive and small-engine hose sizes, so you can match your existing fitting without adapters.
✂️Cut-to-Length Flexibility — Each 5m (≈16.4 ft) roll lets you cut exactly what your routing requires, reducing waste compared to buying fixed-length pre-cut hoses.
🔄Flexible & Kink-Resistant Construction — The soft NBR wall maintains flexibility around bends and tight routing paths, reducing the risk of kinking that can restrict flow in fuel and oil transfer lines.
🌡️Broad Temperature Tolerance — NBR rubber generally performs across a temperature range suitable for typical engine bay and workshop environments, typically from approximately -30°C to +100°C (-22°F to +212°F).
🔧Compatible with Standard Barb Fittings & Hose Clamps — Slips onto standard barbed fittings and secures with worm-drive or spring clamps, making installation straightforward for DIY automotive fuel line repair without special tools.

❓ Frequently Asked Questions

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

Measure the outer diameter of the fitting or barb the hose will slip onto. The hose inner diameter (ID) should match that fitting OD as closely as possible for a secure, leak-free connection. For example, a 6mm (1/4") barb fitting typically pairs with a 6mm ID hose. When in doubt, size down slightly — NBR rubber stretches to grip fittings snugly.

What pressure can this NBR fuel hose handle?

NBR rubber hose of this type is generally rated for low-to-medium pressure applications, typically up to 10–15 bar (145–218 psi) depending on wall thickness and diameter. It is not intended for high-pressure hydraulic circuits. Contact us to confirm the rating for your specific size.

Is this hose suitable for outdoor or under-hood use?

NBR (nitrile butadiene rubber) offers good resistance to petroleum-based fluids and moderate heat, making it suitable for under-hood fuel and oil lines in most automotive applications. For prolonged UV or ozone exposure outdoors, consider adding a protective sleeve or conduit.

What fluids is this hose compatible with?

This hose is generally compatible with petrol (gasoline), diesel, motor oil, hydraulic oil, and many petroleum-based fluids. It is not recommended for use with brake fluid, strong acids, ketones, or aromatic solvents. Always verify chemical compatibility for your specific application.

How do I select the correct length — is 5m enough for my project?

Each roll is 5 meters (approximately 16.4 ft). For most DIY automotive fuel line replacements, 5m is sufficient for a single run. Measure your routing path, add 10–15% for bends and connections, then round up. For longer runs, order multiple rolls.

What is the difference between inner diameter and outer diameter, and which should I match to my fitting?

Inner diameter (ID) is the bore size — the measurement of the hollow channel fluid flows through. Outer diameter (OD) is the total width of the hose including the rubber wall. Always match the hose ID to your fitting's barb or nipple OD for a proper seal. The OD determines clearance through grommets or clamps.

Can I cut this hose to a shorter length?

Yes. NBR rubber hose cuts cleanly with a sharp utility knife or hose cutter. A straight, square cut ensures the best seal against barb fittings. Avoid sawing motions that can leave ragged edges.
