dojobkinb 1/2" (12mm) Fuel Line Hose 20FT — NBR Rubber Push-Lock, 300 PSI Working Pressure

dojobkinb 1/2" (12mm) ID fuel line hose is a 20-foot NBR rubber push-lock hose rated for continuous use with gasoline, diesel, biodiesel and other fluids at working pressures up to 300 PSI.

This 20-foot fuel hose from dojobkinb combines nitrile-butadiene rubber (NBR) construction with push-lock compatibility to support automotive and small-engine fuel routing, oil cooling lines, and other fluid-transfer applications. It is built for a wide temperature range and offers wear resistance and high burst strength, making it suitable for many under-hood and equipment uses when the application pressure ratings are followed.

How does this hose perform under heat, cold and pressure?

The NBR compound maintains flexibility from very low temperatures up to high operating heat, while resisting swell from fuels and oils. It has a specified working temperature range from -40°F to 257°F and a working pressure rating of 300 PSI, with a considerably higher burst pressure for safety margins.

• Operating temperature: -40°F to 257°F
• Working pressure: 300 PSI
• Burst pressure: 1160 PSI
• NBR material resists fuel/oil swelling and abrasion

What fluids and systems is the hose compatible with?

This fuel line is compatible with gasoline, diesel, biodiesel blends and many lubricants, plus water and compressed air in non-critical applications. Always verify chemical compatibility and system pressure before final installation, especially with aggressive additives or specialty fuels.

• Compatible: gasoline, diesel, biodiesel, oil, grease, water, air
• Not for unspecified chemical service without testing
• Suitable for fuel systems, oil cooling, and vapor lines

How do I size and install the 1/2" ID push-lock fuel hose?

The hose inner diameter is 1/2" (12mm) with an outer diameter of about 0.78" (20mm), supplied in a continuous 20-foot length for routing and trim. Use proper push-lock fittings or clamps rated for fuel service, cut squarely, and avoid sharp bends or contact with hot exhaust components.

• ID: 1/2" (12mm); OD: 0.78" (20mm); Length: 20FT
• Use fuel-rated clamps or push-lock fittings for leak-free connections
• Avoid kinking; keep away from exhaust and moving parts

How durable is the hose for workshop and on-vehicle use?

The nitrile rubber outer compound is chosen for wear resistance and long service life in mechanical environments. With appropriate installation and routings — avoiding abrasion points and extreme heat sources — it serves well in automotive and equipment fuel or fluid lines.

• Premium NBR material for wear and heat resistance
• Designed for repeated handling and secure fittings
• Inspect regularly for wear, cracks or fuel permeation

Who is this for? The dojobkinb 1/2" (12mm) ID 20FT NBR fuel hose is aimed at mechanics, hobbyists, fleet technicians and DIYers who need a reliable, fuel-compatible hose for automotive, marine or equipment fluid routing. It suits projects that require mid-range pressure capability, broad temperature tolerance, and compatibility with common fuels and oils. If you require hoses for specialized chemicals, turbocharger oil lines, or systems with higher-than-specified pressures, choose materials and ratings matched to those demands. For typical fuel lines, oil coolers and vapor routing where a push-lock installation is preferred, this hose provides a practical, long-length solution.
