dojobkinb 1/4" (6mm) NBR Fuel Line Hose 25ft — High-Pressure 300 PSI, Heat-Resistant

dojobkinb 1/4" (6mm) inside-diameter NBR fuel line — 25 feet of push-lock hose built for high-pressure automotive fuel and fluid routing.

This 25-foot roll of NBR (nitrile rubber) fuel hose is engineered for engine bays, fuel lines, and fluid transfer tasks where durability and pressure resistance matter. The hose has a 1/4" (6mm) inner diameter and a reinforced outer profile to stand up to high temperatures, chemical exposure, and repeated installation cycles. It’s sized to suit many common automotive fittings and push-lock connectors while offering broad compatibility with fuels and oils.

How tough is this hose under heat and pressure?

The hose is rated for continuous operation across a wide temperature band and for sustained working pressures common in fuel systems. Its construction balances flexibility with reinforcement so it resists collapse, swelling, and pressure-related deformation.

• Operating temperature range: -40°F to 257°F (-40°C to 125°C)
• Working pressure: up to 300 PSI for routine applications
• Burst pressure: approximately 1160 PSI for safety margins
• NBR compound resists heat, oil, and fuel-induced swelling

Which fluids and systems are compatible with this NBR hose?

NBR (nitrile) material was selected for broad chemical compatibility with petroleum-based fluids, making it suitable for many automotive and workshop uses. Always confirm compatibility and pressure needs for your specific application before installing.

• Compatible with gasoline, diesel, biodiesel, and many oil blends
• Accepts grease, oil cooling lines, and some water/air uses
• Not intended for some strong solvents or prolonged contact with certain chemicals—verify beforehand
• Designed for fuel delivery, return lines, and general fluid routing in vehicles

How easy is it to install and what fittings work with it?

The hose’s 1/4" ID is a common size for push-lock and barb fittings, allowing quick connections without special tools in many cases. Its flexible yet resilient wall makes trimming, clamping, and routing straightforward for DIYers and technicians alike.

• Inner diameter: 1/4" (6mm); outer diameter: 0.49" (12.5mm)
• 25-foot length provides ample material for multiple runs or spares
• Works with standard push-lock, barbed, and crimp-style clamps
• Easily cut to length with utility knife or hose cutter

Who is this for? This dojobkinb NBR fuel hose suits mechanics, home garage enthusiasts, and builders of small engines who need a flexible, fuel-compatible line rated for elevated pressures and temperatures. It’s a solid choice for replacing worn lines, fabricating custom-length fuel runs, or stocking a shop with a reliable, multipurpose hose. If your application involves high-pressure hydraulics, strong solvents, or manufacturer-specific OEM requirements, cross-check specifications before use. For typical automotive fuel and oil routing where compatibility with gasoline, diesel, and oil matters, this hose offers a practical balance of performance, value, and ease of installation.
