EVIL ENERGY 5/16" Fuel Hose NBR Rubber SAE 30R7 10ft — 300 PSI, Oil-Resistant

EVIL ENERGY's 5/16" NBR fuel hose is a SAE 30R7–rated, oil-resistant rubber line supplied in a 10-foot length and engineered for up to 300 PSI working pressure.

This fuel hose combines nitrile butadiene rubber (NBR) with a braided polyester reinforcement to deliver chemical resistance, abrasion durability and consistent performance across a wide temperature range. Sized with a 5/16" (8 mm) inner diameter and a 9/16" (14 mm) outer diameter, the hose is built to meet SAE 30R7 specifications and suit fuel, diesel, gasoline, biodiesel and oil-handling applications where flexibility and reliability matter.

What are the key technical specifications of this 5/16" fuel hose?

The hose is designed with clear dimensional and pressure ratings so you can confirm fit and safety before installation. Its construction and limits suit many common fuel-system tasks without over-specifying for simple runs.

• Inner diameter: 5/16" (8 mm); outer diameter: 9/16" (14 mm).
• Wall thickness approximately 4 mm; minimum bend radius 3.14" (80 mm).
• Working pressure: 300 PSI; burst pressure: 1200 PSI.
• Temperature tolerance: −40°F to 257°F (−40°C to 125°C).

Which fluids and environments is this hose compatible with?

The NBR elastomer and polyester braid provide good resistance to oils and fuels commonly used in engines and industrial equipment. It is intended for fuel, diesel, gasoline and biodiesel as well as some greases and oil-carrying lines, but confirm chemical compatibility for specialty fluids.

• Suitable for gasoline, diesel, biodiesel, and many oil-based fluids.
• Not recommended for concentrated solvents or certain aggressive chemicals—verify if unsure.
• Works in hot engine compartments and cold-start conditions across its rated temperature span.

How does the hose perform during installation and routine use?

Its 10-foot length and flexible NBR construction make routing straightforward in tight engine bays or equipment compartments. The braided polyester reinforcement keeps the hose dimensionally stable under pressure and reduces kinking risk at bends above the minimum radius.

• 10-foot length ready for cutter-and-fit installations; cut to custom lengths as needed.
• Minimum bend radius 3.14" (80 mm) to avoid deformation or flow restriction.
• Braided reinforcement improves crush and abrasion resistance for long-term service.

Does this product meet industry standards and where is it commonly used?

The hose is produced to meet SAE 30R7 expectations, a widely recognized standard for fuel and oil lines, and is used across automotive, marine, small engine and industrial equipment applications. Use correct clamps and fittings rated for fuel systems when installing.

• Manufactured to SAE 30R7-style construction for fuel and oil system use.
• Typical uses: fuel lines, oil cooling connections, steam emission piping within spec limits.
• Install with fuel-rated clamps and compatible fittings to maintain pressure integrity.

Who is this for? EVIL ENERGY's 5/16" NBR fuel hose is suited for mechanics, repair shops, enthusiasts and equipment builders needing a dependable, oil-resistant fuel line in a 10-foot roll. Choose this hose when you require clear pressure ratings, compatibility with common fuels, and a flexible, reinforced profile for straightforward routing and reliable performance.
