EVIL ENERGY 1/4" Fuel Hose 20ft SAE 30R7 NBR — 300 PSI Oil-Resistant, Flexible

EVIL ENERGY 1/4" SAE 30R7 NBR fuel hose is a 20-foot, oil-resistant push-lock line rated for 300 PSI and built for diesel, gasoline, biodiesel, oil and grease transfer.

This 1/4" (6 mm) inside diameter fuel hose combines nitrile rubber (NBR) with a braided polyester reinforcement to meet SAE 30R7 expectations while offering a compact, flexible line for fuel systems, oil cooling circuits, and general fluid transfer. With a 0.47" (12 mm) outside diameter, 3 mm wall thickness and a minimum bend radius of 2.36" (60 mm), it balances space-saving routing with durability for automotive, marine, small-engine and industrial uses.

How tough is this hose under pressure and temperature?

The hose is engineered for everyday fuel-line demands: a working pressure of 300 PSI with a burst pressure around 1200 PSI, and a broad operating temperature window from -40°F up to 257°F. Those ratings mean it can handle high-pressure feed lines and still resist hardening or softening in extreme climates.

• Working pressure: 300 PSI for steady fuel delivery.
• Burst pressure: approximately 1200 PSI for safety margin.
• Temperature range: -40°F to 257°F to tolerate cold starts and hot engine bays.
• Wall thickness: 3 mm for puncture and abrasion resistance.

What fluids and environments is the EVIL ENERGY 30R7 hose compatible with?

Made from NBR (nitrile rubber) and braided polyester, the hose is formulated to resist oils, fuels and many petroleum-based fluids. It’s suitable for diesel, gasoline, biodiesel blends, oil and grease where SAE 30R7 hose is specified, and stands up to the chemical exposure common in fuel systems and oil-cooling loops.

• Compatible with gasoline, diesel, biodiesel, oil and grease.
• NBR construction resists swelling and degradation from petroleum contact.
• Braided reinforcement improves wear resistance and dimensional stability.
• Meets/exceeds SAE 30R7 standard for fuel line service.

How easy is it to route, cut and install this 1/4" fuel hose?

The 20-foot length gives flexibility for routing through engine bays or equipment enclosures; the minimum bend radius of 2.36" (60 mm) lets you make tight turns without kinking. It’s compatible with push-lock fittings sized for 1/4" ID and can be trimmed cleanly with a straight hose cutter for custom runs.

• Length: 20 feet for versatile installation options.
• ID: 1/4" (6 mm) fits many push-lock and barbed fittings.
• Min bend radius: 2.36" (60 mm) prevents kinks on tight routes.
• Cut and secure with clamps or approved push-lock fittings; use proper hose clamps for pressure applications.

What construction features improve longevity and safety?

The hose's nitrile rubber compound offers inherent oil resistance, while the polyester braid provides tensile strength and abrasion protection. Combined with a generous safety factor between working and burst pressure, these features reduce leak risk and extend service life compared with unreinforced tubing.

• NBR inner tube resists petroleum-based fluid breakdown.
• Polyester braid enhances pressure tolerance and abrasion resistance.
• 3 mm wall thickness protects against external wear and impact.
• SAE 30R7 construction aligns with industry expectations for fuel hose use.

Who is this for? EVIL ENERGY's 1/4" SAE 30R7 NBR fuel hose is suited to mechanics, fabricators and DIYers who need a compact, durable fuel or oil line for cars, boats, motorcycles, generators and small industrial equipment. Choose this hose when you need a space-efficient conduit that tolerates common fuels and oils, resists wear, and installs easily with standard 1/4" fittings.
