EVIL ENERGY 1/2" NBR Fuel Hose SAE 30R7 — 5 ft, 300 PSI Push-Lock, Durable

EVIL ENERGY 1/2" NBR Fuel Hose SAE 30R7 is a 5-foot, oil- and fuel-compatible push-lock line rated for 300 psi working pressure and built to resist heat, wear, and common fuel blends.

This SAE 30R7-spec hose combines a nitrile rubber (NBR) inner tube and braided polyester reinforcement to deliver a flexible, durable fuel line suited for diesel, gasoline, biodiesel and similar hydrocarbons. The hose is cut to a convenient 5-foot length and is designed to meet typical service demands where pressure, chemical compatibility and a compact bend radius matter. Below you’ll find concise answers to common buyer questions and clear technical specifics to help confirm fit and suitability.

How durable is this hose under heat and pressure?

The 30R7 construction uses NBR for oil resistance and a polyester braid for strength, delivering a 300 psi working pressure and a 1200 psi burst rating. It is engineered to operate across a wide temperature band so it performs in most engine bay and outdoor conditions.

• Working pressure: 300 psi
• Burst pressure: 1200 psi
• Temperature range: -40°F to 257°F (-40°C to 125°C)
• Wall thickness: 3 mm for abrasion resistance

Will this hose handle the fuels and fluids I use?

The NBR inner tube is chosen for compatibility with petroleum-based fluids, making it suitable for gasoline, diesel, biodiesel blends, oils and greases. It is not formulated for strong oxidizers or certain solvents, so confirm fluid compatibility for specialty chemicals.

• Compatible media: gasoline, diesel, biodiesel, oil, grease
• Not intended for strong acids, ketones, or highly aggressive solvents
• Meets SAE 30R7 guidance for typical fuel-system service

How easy is it to install and route in tight spaces?

With an inner diameter of 1/2" (13 mm) and an outer diameter of 0.75" (19 mm), the hose is compact yet serviceable, offering a minimum bend radius of 4.7" (120 mm) for tight routing. The push-lock compatible profile works with common fittings used in fuel systems, making clamp and barb installations straightforward.

• Inner diameter (ID): 1/2" (13 mm)
• Outer diameter (OD): 0.75" (19 mm)
• Minimum bend radius: 4.7" (120 mm) for compact routing
• Length: 5 ft cut to size for quick replacements

How does construction affect wear resistance and longevity?

The NBR rubber resists oil swelling and degradation while the braided polyester reinforcement provides tensile strength and puncture resistance. The combined construction reduces abrasion and mechanical wear where the hose contacts fittings, clamps or chassis surfaces.

• Material: NBR (nitrile rubber) inner tube
• Reinforcement: braided polyester fiber for strength
• Wall thickness: 3 mm for improved durability
• Designed to meet/exceed SAE 30R7 expectations

Who is this for? EVIL ENERGY’s 1/2" SAE 30R7 fuel hose is aimed at technicians, hobbyists and fleet operators who need a short, robust replacement or routing section for fuel lines, oil cooling circuits and similar fluid connections. If you require a compact hose with proven fuel compatibility, a 300 psi working rating and a flexible bend profile, this 5-foot NBR line is a practical choice. For specialty fluids or extreme temperature extremes beyond the stated range, consult a materials compatibility guide before installation.
