HBD Industries Fuel Line Hose 1/4 in ID x 25 ft — Black NBR/PVC SAE30R7, E85 & Diesel Safe

HBD Industries 25060 Thermoid SAE30R7 fuel line hose is a 25-foot, 1/4" inside-diameter NBR/PVC hose engineered to carry gasoline (including E85) and diesel across a wide temperature range.

This reinforced rubber hose is built for automotive, agricultural, and small-engine fuel delivery. Constructed with a nitrile (NBR) tube, two-spiral polyester reinforcement, and a PVC/nitrile cover, it balances chemical resistance with flexibility. Manufactured in the USA, the hose meets SAE 30R7 style requirements and is sized for common fuel line installations that need a durable, all-weather solution.

What materials make this hose suitable for gasoline and diesel?

The inner tube is nitrile rubber (NBR), chosen for its compatibility with hydrocarbons and blended fuels like E85. The cover combines PVC and nitrile to resist abrasion, oil, and weathering without sacrificing flexibility.

• NBR tube resists swelling and degradation from fuels.
• Two spiral polyester plies give pressure handling and kink resistance.
• PVC/NBR cover protects against abrasion and ozone exposure.

How does the size and construction affect installation?

At 0.25" ID (1/4") and supplied on a 25-foot roll, this hose fits standard fuel fittings and allows long runs without multiple joins. The two-spiral reinforcement helps maintain shape under clamps and prevents collapse during bends.

• 0.25" inside diameter fits common carburetor and fuel pump fittings.
• 25-foot length reduces the need for splices on many vehicles and equipment.
• Spiral reinforcement keeps hose pliable but stable under vacuum and pressure.

Can this hose handle extreme temperatures and outdoor use?

The hose is rated from -40°F to +257°F, making it usable in cold-start conditions and in high-heat engine compartments. The cover formulation resists cracking from sunlight and ozone, and the materials maintain flexibility across the rated range.

• Low-temperature flexibility prevents brittleness in freezing weather.
• High-temperature resistance helps avoid softening near hot engine areas.
• Cover resists environmental aging for prolonged outdoor service.

Who is this for: mechanics, restorers, and DIYers who need a reliable, American-made fuel hose for cars, trucks, tractors, or small engines. Choose this hose when you want an SAE30R7-style line with proven nitrile fuel compatibility, a practical 25-foot length for routing without excess splices, and a temperature rating suitable for a broad range of climates and engine compartments.
