Pangda 3/8" NBR Fuel Line Hose 20 ft — 300 PSI Transfer Hose for Boats, Small Engines

This durable fuel hose from Pangda is engineered for contractors, mechanics and DIYers who need a reliable fuel supply line for small-engine applications. Made from nitrile butadiene rubber (NBR), the tubing balances flexibility with chemical resistance to common fuels and operating temperatures. It arrives as a single 20 ft length with an inner bore of approximately 3/8" (10 mm) and an outer diameter near 17 mm, making it compatible with many standard fittings and clamps used in marine, automotive and powersports systems.

How does this hose stand up to heat, cold and pressure?

The Pangda NBR hose is designed to handle a wide temperature range and sustained pressure typical of fuel transfer and small engine circulation. Working temperatures span from -40°C up to 120°C and the hose carries a working pressure rating of 300 PSI with a much higher burst rating for safety margin. That makes it suitable for engine bays, boat bilges and other environments where thermal and pressure variations occur.

• Operating temperature range: -40°C to 120°C
• Working pressure: 300 PSI; burst pressure: 1160 PSI
• NBR compound resists common fuel and oil exposure

Will this fit my small engine, boat or motorcycle fuel system?

The hose inner diameter is approximately 3/8" (10 mm), a common size for transfer lines and primer connections on small engines. Its external diameter of about 17 mm accommodates typical hose clamps and barb fittings used in marine, automotive and powersports applications. Check your equipment fittings and any inline components to confirm compatibility before installation.

• Inner diameter: ~3/8" (10 mm)
• Outer diameter: ~17 mm (approx.)
• Works with standard hose clamps and barbed fittings

How should I install and use this fuel hose safely?

Installation is straightforward but should follow safety best practices to prevent leaks and ensure proper fuel flow. Insert the hose fully onto the fitting, secure with an appropriate clamp, and avoid routing near sharp edges or excessive heat sources. If using as a pickup tube inside a tank, pair it with a primer bulb (not included) and ensure no anti-theft filters block the line.

• Use a compatible primer bulb for suction starts; bulb not included
• Secure with proper clamps; avoid kinks and sharp bends
• Keep away from direct exhaust heat and sharp edges

What is the material quality and expected longevity?

The hose is constructed from NBR (nitrile butadiene rubber), a material chosen for its resistance to petroleum products and robust physical properties. NBR resists swelling and softening from gasoline and diesel better than many generic rubbers, and the hose is produced with consistent wall thickness to reduce premature wear. With proper routing and secure fittings, the tubing is suitable for long-term service in many non-pressurized and moderately pressurized fuel applications.

• NBR material resists fuel-induced deterioration
• Manufactured for consistent wall strength and flexibility
• Intended for fuel supply use in small engine systems

Who this is for: Pangda's 3/8" NBR fuel line is geared toward boat owners, small-engine mechanics, motorcycle and ATV enthusiasts, and general maintenance professionals who need a dependable fuel transfer line. It suits installations that require a balance of flexibility, fuel resistance and pressure capability—especially where a 20-foot length and common 3/8" bore match existing fittings. Not intended as a pressurized mainline for large commercial engines without confirming system requirements.
