EVIL ENERGY 1/2" Fuel Hose NBR Rubber 25 ft — SAE 30R7, 300 PSI, oil-resistant

This hose combines nitrile-butadiene rubber (NBR) with braided polyester reinforcement to deliver a durable, oil-resistant fuel line for automotive, marine, agricultural, and industrial fuel-system use. With a compact inner diameter and a thin wall profile, it’s engineered for tight routing, dependable pressure handling, and broad temperature tolerance from -40°F to 257°F.

What are the core specifications and construction details?

The hose has a 1/2" (13 mm) inner diameter and a 0.75" (19 mm) outer diameter, with 3 mm wall thickness and a minimum bend radius of 4.7" (120 mm). It meets SAE 30R7 requirements thanks to its NBR tube and braided polyester cover, balancing flexibility and abrasion resistance.

• Inner diameter: 1/2" (13 mm)
• Outer diameter: 0.75" (19 mm)
• Wall thickness: 3 mm; minimum bend radius: 4.7" (120 mm)
• Reinforcement: braided polyester fiber for pressure and wear resistance

Which fluids and environments is this hose compatible with?

The NBR tube is resistant to petroleum-based fluids, making the line suitable for gasoline, diesel, biodiesel blends, oils, and many greases. It also works in oil cooling and vent/steam emission applications, provided operating conditions stay within temperature and pressure limits.

• Compatible media: gasoline, diesel, biodiesel, engine oil, hydraulic oil, grease
• Temperature rating: -40°F to 257°F for cold starts and high-heat environments
• Do not use with strong oxidizers or solvents outside NBR compatibility

How much pressure can the hose safely handle and what are failure margins?

This hose has a working pressure of 300 psi with a burst pressure rated around 1200 psi, offering a conservative safety margin for typical fuel-system demands. Proper clamps, push-lock fittings, and secure routing are essential to maintain seal integrity under vibration and temperature cycles.

• Working pressure: 300 psi
• Burst pressure: ~1200 psi (four times working pressure)
• Use approved fuel-line clamps or push-lock fittings to prevent leaks

How should I install and care for the EVIL ENERGY fuel hose?

Cut ends square and deburr before attaching fittings; avoid sharp bends near clamps and keep the minimum bend radius in mind when routing. Inspect periodically for abrasion, hardening, or signs of chemical attack and replace if damaged or softened from incompatible fluids.

• Trim cleanly and secure with compatible push-lock or SAE clamps
• Maintain at least a 4.7" (120 mm) bend radius to prevent kinking
• Inspect regularly and replace if cracked, swollen, or excessively worn

Who is this for: Mechanics, fabricators, fleet maintenance teams, and DIY enthusiasts who need a reliable, oil-resistant 1/2" fuel line for engines, pumps, or fuel-transfer assemblies. The 25-foot length provides flexibility for routing and spare inventory, while SAE 30R7 construction and the 300 psi working pressure make it suitable for most light- to medium-duty fuel-system uses. Choose this hose when you require a balance of flexibility, chemical compatibility, and proven reinforcement for long-term service.
