3/8 Inch (10mm) ID Fuel Line Hose 16.4FT NBR Rubber Push

This is a 3/8" (10mm) inner diameter NBR rubber fuel line — 16.4 feet long and rated for 300 PSI working pressure — designed for automotive and engine fuel systems.

Built from premium NBR (nitrile butadiene rubber), this push-lock fuel hose delivers reliable resistance to heat, oil and common engine fuels. With an outer diameter of approximately 2/3" (17mm) and a burst pressure up to 1160 PSI, the hose is suitable for a wide range of fuel-system tasks where flexibility, chemical tolerance and robust pressure performance matter. It performs across a broad temperature range from -40°F to 257°F, making it useful for seasonal and varied-environment vehicle work.

How does this hose perform under engine heat and pressure?

The NBR compound is formulated to tolerate elevated temperatures and repeated pressure cycles without quick degradation. Rated for continuous operation at up to 300 PSI and tested to burst at about 1160 PSI, it balances safety margin with everyday usability for many light- and medium-duty fuel applications.

• Working temperature range: -40°F to 257°F for seasonal reliability.
• Working pressure: 300 PSI for routine fuel-line duties.
• Burst pressure: approximately 1160 PSI for failure threshold context.
• NBR material offers improved oil and heat resistance versus basic rubber.

Which fuels and fluids can I safely run through it?

This hose is compatible with a broad set of automotive and industrial fluids thanks to NBR’s chemical profile. It is suitable for gasoline, diesel, biodiesel blends, light oil, grease, water and air lines when used within its pressure and temperature ratings.

• Approved for gasoline, diesel and biodiesel mixtures for fuel delivery.
• Accepts oils, greases and coolant/air lines in non-critical applications.
• Not recommended for strong acids, ketones, or specialized solvents.
• Always confirm system pressure and chemical compatibility before installation.

What sizes and lengths are provided, and how do I fit it?

This product comes as a single 16.4-foot length with a 3/8" (10mm) inner diameter and an approximate 2/3" (17mm) outer diameter. It is intended for push-lock and barbed fittings commonly used on fuel systems; secure with clamps appropriate to the hose diameter and expected pressure for leak-free operation.

• Inner diameter: 3/8" (10mm) — common for small engine and automotive lines.
• Outer diameter: ~2/3" (17mm) for clamp selection and fitment checks.
• Length: 16.4FT (5 meters) — enough for multiple runs or spares.
• Use quality clamps and inspect fittings regularly for wear.

Is this hose durable for workshop and outdoor use?

Yes — the NBR construction offers good wear resistance and durability for typical workshop and outdoor vehicle tasks. Its combination of temperature range and material toughness makes it suited to both storage and active engine-bay routing when protected from sharp edges and excessive abrasion.

• NBR delivers wear and abrasion resistance for repeated handling.
• Temperature span supports cold starts and hot-engine environments.
• Inspect for cuts, kinks or chemical damage before each use.
• Trim, clean and secure ends to prevent contamination and leaks.

Who is this for: This 3/8" NBR fuel line is for DIY mechanics, small-engine technicians and fleet maintenance teams needing a flexible, chemically resistant tubing option. It fits projects that require a mid-pressure fuel hose—such as fuel return lines, carburetor connections, small injector feeds and general-purpose fluid routing—where compatibility with gasoline, diesel and light oils is required. Not intended for oxygen service, high-temperature turbo oil lines, or aggressive solvent handling without separate compatibility checks.
