EVIL ENERGY 3/8 in NBR Fuel Hose 10ft SAE 30R7 — 300 PSI Oil-Resistant Braided

EVIL ENERGY's 3/8" NBR push-lock fuel hose is a 10-foot, SAE 30R7–rated fuel line engineered to carry gasoline, diesel, biodiesel, oil and grease under working pressures up to 300 PSI.

This heavy-duty fuel hose combines an oil-resistant nitrile rubber (NBR) tube with braided polyester reinforcement to meet and exceed SAE 30R7 specifications. Built for service temperatures from -40°F to 257°F, it delivers consistent flow and abrasion resistance in automotive, industrial, marine and equipment fuel systems. The 3/8" (9.5mm) inside diameter and 3mm wall thickness provide a reliable balance of flexibility and strength while the minimum bend radius of 3.9" (100mm) helps routing in tight engine bays.

What fluids can this hose safely transport?

The NBR inner tube is formulated for compatibility with a broad range of hydrocarbon-based fluids. Use it for gasoline, diesel, biodiesel blends, engine oil, hydraulic oil and many greases—making it suitable for fuel lines and oil-cooling circuits.

• Compatible with gasoline, diesel, biodiesel and most engine oils
• Resists swelling and degradation from petroleum-based fuels
• Not intended for pure alcohols or strong solvents unless verified
• Suitable for fuel-return, feed and oil-cooling hoses

How strong and flexible is the 3/8" SAE 30R7 hose?

This hose is designed for demanding operating conditions: a 300 PSI working pressure and 1,200 PSI burst pressure give a wide safety margin for typical fuel-system use. The braided polyester reinforcement increases tensile strength while the 3mm wall keeps the line flexible enough for tight routing.

• Working pressure: 300 PSI; burst pressure: 1,200 PSI
• Minimum bend radius: 3.9" (100mm) for compact installations
• Wall thickness: 3mm balances durability and pliability
• 3/8" (9.5mm) ID fits standard push-lock fittings and clamps

What temperature range and environmental conditions can it handle?

The NBR compound and polyester braid allow reliable performance across a broad temperature span, from -40°F up to 257°F. That makes the hose suitable for cold starts and high under-hood temperatures while providing resistance to oil and abrasion.

• Operating temperature: -40°F to 257°F (-40°C to 125°C)
• Good oil and wear resistance for automotive and industrial exposures
• Polyester braid limits stretch and resists mechanical wear
• Store away from ozone and strong oxidizers for maximum life
