NexaNova marine fuel hose 5/16" (8.1 mm) — 10 ft Type A1-15 NBR rubber, SAE J1527, 300 PSI

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

This heavy-duty fuel hose is engineered for marine environments where reliable fuel transfer is essential. With an internal diameter of 5/16" (8.1 mm) and an outer diameter of 9/16" (14.5 mm), the hose balances flow capacity and routing flexibility. Constructed from NBR rubber, it resists common marine fuels including gasoline, diesel, biodiesel, kerosene and ethanol blends. Rated for a working pressure of 300 PSI and a burst pressure of 900 PSI, it suits many onboard fuel supply applications within a broad temperature range.

How does this hose handle different marine fuels?

The NexaNova hose uses NBR (nitrile butadiene rubber) compounds formulated to tolerate petroleum fuels and typical ethanol blends without rapid degradation. It’s intended for use where compatibility with gasoline, diesel, biodiesel and kerosene is required, helping minimize swelling and loss of flexibility.

• Compatible with gasoline, diesel, biodiesel, kerosene and ethanol blends
• NBR inner construction resists fuel swell and permeation
• Meets common marine material expectations for fuel resistance

What sizes and routing constraints should I plan for?

The hose inner diameter is 5/16" (8.1 mm), outer diameter 9/16" (14.5 mm), and the minimum bending radius is 75 mm. Those dimensions let you calculate fittings, clamps and routing through bulkheads and tight engine compartments without kinking.

• ID: 5/16" (8.1 mm) for flow and fitting selection
• OD: 9/16" (14.5 mm) for clamp and pass-through sizing
• Minimum bend radius: 75 mm to avoid kinks and flow restriction

Is the hose durable and safe for marine use?

The hose is manufactured to SAE J1527 Type A1-15 guidelines, reflecting a recognized marine fuel hose standard. Its rated working pressure (300 PSI) and burst pressure (900 PSI) make it suitable for many fuel delivery setups; the operating temperature window covers -20 °F to 221 °F (-30 °C to 105 °C) for typical onboard environments.

• SAE J1527 compliant for assurance of material and construction
• Working pressure: 300 PSI; burst pressure: 900 PSI for safety margin
• Temperature range: -20 °F to 221 °F (-30 °C to 105 °C)

How do I install and maintain this fuel hose?

Cut the hose squarely to length and use corrosion-resistant clamps rated for marine fuel systems. Inspect fittings and hose ends periodically for wear, chafe and chemical attack, and replace the hose if you detect hardening, cracking or excessive softening. Always verify fuel system compatibility and local regulations before installation.

• Use appropriate marine-grade fittings and clamps for secure connections
• Check hose condition regularly; replace if damaged or degraded
• Confirm size and compatibility before cutting and installing

Who this is for: NexaNova's 5/16" Type A1-15 marine fuel hose is aimed at boat owners, marine technicians and fleet operators needing a durable, SAE-compliant fuel line for small- to medium-displacement outboards, inboards and auxiliary ship equipment. Choose this hose when you require a proven NBR construction, clear size specifications (5/16" ID, 9/16" OD), and a 10-foot length for flexible routing. Please verify hose dimensions and compatibility with your fittings and fuel type before purchase.
