EVIL ENERGY 3/16" Fuel Hose 10ft SAE 30R7 NBR Rubber — 300 PSI, -40° to 257°F

This 3/16-inch (5mm) inner diameter fuel hose combines oil-resistant NBR rubber with a braided polyester reinforcement to deliver a compact, flexible line for fuel systems, oil cooling circuits and related fluid-transfer tasks. Built to meet and exceed SAE 30R7 standards, the hose is engineered for demanding automotive and industrial environments where chemical resistance, abrasion durability and a wide temperature range are needed.

How does this hose handle different fuels and oils?

The hose’s NBR (nitrile butadiene rubber) compound provides strong resistance to hydrocarbons and common fuel blends, reducing swelling and premature failure when exposed to diesel, gasoline, biodiesel and lubricating oils. Braided polyester reinforcement keeps the structure stable under pressure and reduces elongation.

• Compatible media: diesel, gasoline, biodiesel, oil, grease.
• NBR material minimizes degradation from hydrocarbon exposure.
• Braided fiber prevents expansion under pressure and improves durability.

Can it handle the pressures and temperatures of my system?

The hose is rated for a 300 PSI working pressure and a 1200 PSI burst pressure, providing a robust safety margin for many fuel and oil-transfer applications. Temperature resistance ranges from -40°F to 257°F, so it performs across cold starts and hot engine compartments without immediate hardening or softening.

• Working pressure: 300 PSI; burst: 1200 PSI for safety reserve.
• Operating temperatures: -40°F to 257°F for wide environmental tolerance.
• Minimum bend radius: 2.0 inches (50mm) for tight routing with minimal kinking.

What are the physical dimensions and installation considerations?

This hose has an internal diameter of 3/16" (5mm) and an outer diameter of 0.43" (11mm) with a wall thickness of roughly 3mm, making it a slim, flexible option for compact assemblies. Its minimum bend radius is 2.0" (50mm), so plan routing to avoid sharper bends that could reduce service life.

• Inner diameter: 3/16" (5mm); outer diameter: 0.43" (11mm); wall: ~3mm.
• Minimum bend radius: 2.0" (50mm) — use clamps or guides to prevent tight kinks.
• Length: 10 feet (3.05 m) — allows multiple runs or precise trimming to size.

How durable and maintenance-friendly is the EVIL ENERGY 30R7 hose?

Designed to exceed SAE 30R7 criteria, the combination of NBR rubber and braided polyester gives strong abrasion resistance and wear life under vibration and engine movement. Routine inspection for cracks, hardening, or external abrasion will help maximize service life, and the hose is straightforward to cut and attach with compatible push-lock or clamp fittings.

• Construction: NBR rubber with braided polyester reinforcement for abrasion resistance.
• Meets/exceeds SAE 30R7 standards for fuel-line applications.
• Easy to trim and install with standard hose clamps or push-lock fittings.

Who is this for? Installers, mechanics and DIY vehicle owners who need a compact, oil-resistant fuel line for small-diameter fuel or oil circuits will find this hose suitable. It’s aimed at applications requiring SAE 30R7 performance in tight spaces: fuel systems, oil cooling lines, secondary return lines, and other light-duty fluid-transfer tasks in automotive, powersports, marine and light industrial settings. Always match hose material and pressure ratings to your system and follow proper installation practices to ensure long-term reliability.
