LSDZWORK 3/8" Marine Fuel Hose 3/8in ID (9.5mm) — NBR Rubber, SAE J1527 Type A1-15, Flexible Durable Feed Line

LSDZWORK 3/8" Marine Fuel Hose is a heavy‑duty NBR rubber fuel feed line built to SAE J1527 standards for reliable gasoline, diesel and E85 delivery in marine and power applications.

This 3/8" (9.5 mm ID) marine fuel hose is designed for fuel-feed, vapor return and oil‑cooling runs where durability and flexibility matter. Made from premium nitrile butadiene rubber (NBR) and manufactured to SAE J1527 / Type A1-15 guidance, the hose resists aging, remains flexible at typical operating temperatures and can be cut to length for custom installations. It’s optimized for boats, small engines, generators and other applications that need a resilient, compatible fuel line.

How does this hose meet marine and automotive fuel standards?

The hose is produced to align with SAE J1527 Type A1-15 criteria for fuel system hoses, ensuring consistent dimensions and material properties. That standardization helps installers match fittings and maintain predictable performance under marine or vehicle conditions.

• Manufactured to SAE J1527 Type A1-15 specifications
• Constructed from NBR for fuel resistance and longevity
• Consistent 3/8" (9.5 mm) inside diameter for standard connectors
• Outer diameter ~17 mm for clamp and fitting compatibility

What fuels and environments is the NBR hose compatible with?

This rubber fuel line handles common hydrocarbons used in small engines and boats, including gasoline, diesel and many ethanol blends such as E85. Its NBR compound offers strong resistance to oil and fuel swelling, though extreme chemical exposures or additives outside normal fuel formulations should be avoided.

• Compatible with gasoline, diesel and ethanol blends (e.g., E85)
• Suitable for fuel-feed, return lines and oil‑cooling circuits
• Not intended for prolonged exposure to aggressive solvents
• Check pressure and temperature range against your system needs

How easy is it to fit and install this 3/8" feed line?

The hose is supplied in extra‑long lengths that you can trim to size, allowing on‑site customization and reducing the number of fittings needed. Its 17 mm outer diameter accepts standard clamps and marine fittings, while an 80 mm minimum bending radius helps plan routing with minimal kinking.

• Inside diameter: 3/8" (9.5 mm); outer diameter: ~17 mm
• Minimum bending radius: 80 mm to avoid collapse or kinks
• Cut to length for clean, secure terminations with clamps or fittings
• Extra-long reels reduce joints and potential leak points

Who is this product for? The LSDZWORK 3/8" Marine Fuel Hose is aimed at marine technicians, small-engine mechanics, DIY boat owners and anyone who needs a robust, fuel-compatible rubber line for fuel-feed, return or cooling circuits. Choose this hose if you want a standardized, easy-to-cut NBR line that handles gasoline, diesel and common ethanol blends, fits standard clamps and holds up to typical marine and equipment environments. Verify your system’s pressure and temperature requirements before installation to ensure compatibility.
