EVIL ENERGY 3/8 in Fuel Hose 30 ft — NBR SAE 30R7, 300 PSI oil-resistant and flexible

EVIL ENERGY's 3/8" NBR SAE 30R7 fuel hose is a 30-foot, oil-resistant line rated for 300 PSI working pressure and compatible with gasoline, diesel, biodiesel and oils.

This heavy-duty aftermarket fuel line is engineered for fuel-system, oil-cooling and general petroleum transfer use where SAE 30R7 performance is required. Built with an NBR (nitrile rubber) tube and a braided polyester reinforcement, the hose balances flexibility and abrasion resistance while maintaining a wide temperature tolerance for cold starts and hot operating conditions.

How strong and flexible is this hose for tight routing?

The hose combines a 3 mm wall thickness and braided polyester fiber to give a durable yet bendable profile that routes through engine bays and tight machinery spaces without kinking. Its minimum bend radius of 3.9" (100 mm) avoids stress at fittings when installed around bends.

• Inner diameter (ID): 3/8" (9.5 mm)
• Outer diameter (OD): 0.67" (17 mm)
• Minimum bend radius: 3.9" (100 mm)
• Wall thickness: 3 mm for impact and crush resistance

What pressure and temperature ranges can I expect?

This hose is specified for 300 PSI continuous working pressure and a 1,200 PSI burst rating to provide operating margin for most fuel and oil-handling applications. It also handles extreme environments with a temperature range from -40°F up to 257°F (-40°C to 125°C).

• Working pressure: 300 PSI for routine service
• Burst pressure: 1,200 PSI for safety margin
• Temperature range: -40°F to 257°F for cold and high-heat use

Which fluids are compatible with the NBR 30R7 hose?

The nitrile rubber tube formulation is selected for resistance to petroleum-based fluids, making it suitable for gasoline, diesel, biodiesel blends, oils and common greases. It is not formulated for prolonged exposure to strong oxidizers, concentrated solvents, or high-percentage alcohol fuels without prior compatibility checks.

• Compatible: gasoline, diesel, biodiesel, motor oil, hydraulic oil, grease
• Not recommended: strong oxidizing agents and certain chemical solvents
• Meets SAE 30R7 performance expectations for fuel-system use

How does this hose meet installation and durability needs?

The hose construction combines an oil-resistant NBR inner tube with a polyester braid reinforcement and a robust outer cover to resist abrasion, oil exposure and routine wear. It arrives in a 30-foot length for flexible cutting to size and is compatible with standard push-lock and crimp fittings sized for 3/8" ID hose.

• Material: nitrile rubber (NBR) tube plus braided polyester reinforcement
• Length: 30 feet for multiple cuts or longer runs
• Fitting compatibility: push-lock and crimp-style fittings for 3/8" hose

Who is this product for? Mechanics, custom-builders, fleet technicians and hobbyists who need a reliable, oil-resistant fuel or oil line for automotive, marine, agricultural, or industrial equipment will find this hose useful. It's intended for installations requiring SAE 30R7 performance attributes: flexible routing, oil compatibility, wide temperature tolerance and a 300 PSI working pressure. Always confirm chemical compatibility and correct fitting selection for safe, long-term service.
