NexaNova 5/16" Marine Fuel Line Hose Type A1-15 — 10ft NBR Rubber, SAE J1527, 300 PSI

NexaNova 5/16" marine fuel line hose (Type A1-15) is a 10-foot NBR rubber hose built to SAE J1527 standards for safe, reliable fuel delivery in boats and ship equipment.

This heavy-duty marine fuel hose is engineered to handle gasoline, diesel, biodiesel, kerosene and ethanol blends while resisting the wear and conditions encountered on board. With a 5/16" (8.1 mm) inner diameter and robust rubber construction, it balances flexibility with strength for routing in tight engine compartments. The hose meets SAE J1527 requirements and is rated for a broad temperature range, making it a practical replacement or spare for marine fuel systems.

How does this hose handle different fuels and marine conditions?

The NexaNova hose uses an NBR rubber compound formulated to tolerate common liquid fuels and many ethanol blends, minimizing softening or swelling that can occur with incompatible materials. Its construction reduces permeation and resists degradation from oil and fuel exposure found on vessels of all sizes.

• Compatible with gasoline, diesel, biodiesel, kerosene and ethanol blends
• NBR rubber resists fuel swelling and oil exposure
• Designed for marine environments where fuel contact and vibration are frequent

What are the hose dimensions and pressure ratings?

This model has a 5/16" (8.1 mm) inner diameter and a 9/16" (14.5 mm) outer diameter, supplied as a 10-foot length for flexible installation. It is rated for everyday marine fuel system pressures and engineered safety margins for temporary overpressure events.

• Inner diameter: 5/16" (8.1 mm); outer diameter: 9/16" (14.5 mm)
• Working pressure: 300 PSI; burst pressure: 900 PSI
• Minimum bending radius: 75 mm for routing in confined spaces

Can it withstand temperature extremes and on-board use?

The hose is specified to operate across a wide temperature span so it performs reliably in seasonal and climate variations encountered at sea. The rated range covers typical cold starts and hot-engine environments without compromising flexibility or strength.

• Temperature range: -20 °F to 221 °F (-30 °C to 105 °C)
• Durable construction meant for vibration and movement aboard boats and ships
• Meets SAE J1527 standard for marine fuel hoses

Who is this for? Boat owners, small commercial operators, marine mechanics, and equipment technicians who need a dependable, standards-compliant fuel line will find the NexaNova 5/16" Type A1-15 hose appropriate. It’s suited for inboard and outboard fuel supply lines, replacement runs in engine rooms, and as a spare on vessels where compatibility with gasoline, diesel or ethanol-blended fuels is required. Always verify hose inner diameter and fittings match your system before installing.
