GIWOSK 25ft 1/4" ID Fuel Line Hose — NBR Rubber, 300 PSI High-Pressure Marine & Motorcycle Fuel Tube

GIWOSK 25ft 1/4" ID NBR fuel line hose is a durable, flexible high-pressure tube designed for gasoline, diesel and small-engine fuel systems. This heavy-duty 25-foot hose pairs a compact 1/4" inner diameter with NBR (nitrile) rubber construction to deliver dependable fuel transfer for motorcycles, outboards, small engines and many marine installations. Built to tolerate a wide temperature span and rated for 300 psi working pressure, it aims to simplify routing and replacement jobs while resisting fuel, oil and standard automotive fluids.

How will this hose perform in hot or cold conditions?

The GIWOSK NBR formulation resists hardening in cold and softening in heat, giving a stable service window from -40°F to 257°F. That range covers most seasonal marine and outdoor automotive uses, reducing the risk of cracking or swelling under normal operating temperatures.

• Operating temperature range: -40°F to 257°F
• Material: NBR rubber for fuel and oil resistance
• Maintains flexibility across temperature extremes

Is this hose safe for pressurized fuel systems and what are the limits?

This tube is specified for a working pressure of 300 psi and a burst pressure near 1160 psi, making it suitable for many high-pressure small-engine and accessory fuel lines. Always verify your system's peak pressures and use appropriate clamps and fittings to ensure safe installation.

• Working pressure: 300 psi for continuous operation
• Burst pressure: approximately 1160 psi for short-term resilience
• Use with correct hose clamps and rated fittings only

Which fuels and fluids can be used with this hose?

The hose is formulated to tolerate gasoline, diesel, biodiesel blends, motor oil and water commonly found in automotive and marine contexts. Confirm chemical compatibility for specialty fuels or additives before use to avoid premature deterioration.

• Compatible: gasoline, diesel, biodiesel blends, motor oil, water
• Not designed for strong solvents or aggressive chemicals without verification
• Inspect periodically when using ethanol-rich or unconventional fuels

How easy is it to install and size for my project?

At 1/4" inner diameter (about 6 mm) and 1/2" outer diameter (12 mm), the hose fits standard small-engine fittings and many motorcycle or marine clamps. The 25ft length gives ample routing flexibility for longer runs or to cut multiple segments for several connections.

• Inner diameter: 1/4" (6 mm) — common small-engine size
• Outer diameter: 1/2" (12 mm) — fits standard hose clamps
• Length: full 25 ft for long runs or multiple cuts

Who is this for? The GIWOSK 25ft 1/4" NBR fuel line is aimed at DIY mechanics, marine technicians and riders who need a reliable, flexible replacement tube for fuel routing and repairs. It’s a practical choice when you want a long length to customize runs, replace brittle original hoses, or stock up for multiple small-engine or boat maintenance tasks. Check your system’s pressure and chemical needs before installing, and use approved clamps and fittings for a secure, leak-free connection.

FAQ

Q: Can this hose handle ethanol-blended fuels?

A: GIWOSK NBR resists common ethanol blends, but confirm compatibility for high ethanol concentrations and inspect regularly.

Q: What fittings and clamps should I use?

A: Use fuel-rated clamps and fittings sized for 1/4" ID (6mm) to ensure a secure, leak-free connection.
