EVIL ENERGY 3/8" Fuel Hose Line Push-Lock SAE 30R7 20ft NBR 300 PSI — Reinforced, Oil-Resistant

EVIL ENERGY 3/8" Fuel Hose Line Push Lock SAE 30R7 is a 20‑foot, NBR‑lined fuel hose rated to 300 PSI for diesel, gasoline, biodiesel and oil applications.

This reinforced 30R7 fuel hose combines a nitrile butadiene rubber (NBR) inner tube with braided polyester reinforcement to deliver oil resistance, abrasion durability and a wide usable temperature range. It’s designed to meet SAE 30R7 performance expectations and is suitable for fuel transfer, return lines, oil cooling, and similar systems where a compact, flexible hose is needed.

How does this hose hold up under pressure and temperature extremes?

The EVIL ENERGY hose is engineered for demanding operating conditions with a working pressure of 300 PSI and a burst pressure around 1200 PSI, providing a large safety margin for many fuel and oil line uses. Its NBR construction stays resilient across a broad temperature span, maintaining flexibility in cold and stability in heat.

• Working pressure: 300 PSI
• Burst pressure: approx. 1200 PSI
• Temperature range: -40°F to 257°F
• Wall thickness: 3.2 mm for durability

Which fluids and systems is this NBR hose compatible with?

The inner NBR tube resists swelling and degradation from common hydrocarbons, making this hose appropriate for diesel, gasoline, biodiesel blends, oil and many lubricants. It’s commonly used for fuel delivery lines, oil cooling circuits and steam emission control where SAE 30R7 compatibility is required.

• Compatible with diesel, gasoline and biodiesel
• Suitable for oils, greases and petroleum‑based fluids
• Not intended for strong acids, ketones or concentrated solvents

What are the physical dimensions and installation considerations?

The hose has a 3/8" (9.5 mm) inner diameter and a 0.63" (16 mm) outer diameter, with a minimum bend radius of about 3.9" (100 mm). Those dimensions make it compact enough for tight routing while still allowing good flow; ensure fittings and clamps match the ID for leak‑free push‑lock or crimp connections.

• ID: 3/8" (9.5 mm); OD: 0.63" (16 mm)
• Minimum bend radius: 3.9" (100 mm)
• Length: 20 ft continuous coil for multiple runs
• Recommended: use proper clamps and check for chafing or sharp bends

How durable is the hose for repeated mechanical wear and outdoor use?

The braided polyester overcover provides strength against abrasion and external wear while the NBR inner layer resists oil attack, extending service life in engine bays and equipment exposed to vibration. Regular inspection at attachment points and routing paths will maximize longevity.

• Reinforced polyester braid for tensile strength
• NBR inner tube resists oil and fuel degradation
• Wall thickness (3.2 mm) balances flexibility with toughness
• Designed to meet or exceed SAE 30R7 requirements

Who is this for: technicians, vehicle owners and equipment assemblers who need a reliable, compact fuel or oil hose for fuel lines, return systems, oil coolers and related applications. If you require a 3/8" ID hose with strong oil resistance, a 20‑foot length for routing flexibility, and SAE 30R7 compatibility, the EVIL ENERGY 3/8" NBR fuel hose is engineered to fit those needs. Always follow local codes for fuel system installation, use correct fittings and clamps, and inspect hose runs periodically for wear.
