Vintruep AN6 Nylon Braided Fuel Hose Black 19.8ft — CPE Core, 750 PSI Working for Fuel & Oil Lines

Vintruep 6AN CPE braided fuel line is a heavy‑duty AN6 hose designed for fuel, oil, transmission and vacuum systems that delivers high pressure capacity and abrasion resistance in extreme temperatures.

Built with a three‑layer construction — a CPE synthetic rubber core, a 304 stainless steel reinforcement braid, and a nylon outer sheath — this AN6 fuel hose balances flexibility with ruggedness for automotive and motorsport plumbing. It’s compatible with gasoline, diesel, engine oil, transmission fluid and hydraulic lines, and fits standard 6AN swivel fittings for assembly. Available in extended lengths, the hose is aimed at installations that need reliable pressure handling and wear protection.

How does this hose perform under pressure and heat?

The Vintruep 6AN braided line is rated for demanding conditions, offering a working pressure of up to 750 PSI and a burst rating up to 2,250 PSI. Its material choices provide operational stability across a broad temperature span, so it remains functional in both cold starts and hot engine bays.

• Maximum working pressure: 750 PSI
• Burst pressure: 2,250 PSI
• Temperature range: -22°F to 248°F
• 304 stainless braid for added pressure tolerance

What fluids and systems can I use this line with?

This AN6 hose handles a wide variety of automotive liquids and gases, making it suitable for fuel supply and return lines, oil cooling loops, transmission lines, turbo plumbing and vacuum circuits. The CPE inner tube is chemically compatible with common fuels and lubricants used in performance and street vehicles.

• Compatible with gasoline, diesel, and racing fuels
• Suitable for engine oil and transmission fluids
• Works for hydraulic fluid and vacuum applications
• Recommended for fuel rails, oil coolers, and turbo lines

How do size and installation affect fitment?

The hose has an inner diameter of 0.31 inch (AN6 standard) and an outer diameter of approximately 0.56 inch, so it pairs with 6AN swivel fittings and standard AN end fittings. Because the CPE core has some stiffness, installations should avoid tight radius bends to prevent kinking or premature wear.

• Inner diameter: 0.31 in (AN6)
• Outer diameter: ~0.56 in
• Lengths available: 10 ft and 20 ft (sold options include 19.8 ft equivalent)
• Minimum bend radius: 2.5 in — avoid sharp turns

What makes this hose durable and serviceable?

Durability comes from the layered design: a chemical‑resistant CPE tube, a stainless steel reinforcement braid to resist burst and abrasion, and a nylon jacket to protect against chafing and UV. The materials and build quality aim to extend service life in road and track environments while minimizing leaks and degradation.

• Three‑layer construction for strength and wear resistance
• Nylon outer braid protects against abrasion and weathering
• 304 stainless steel middle braid improves anti‑kink behavior
• Customer support available for fitting and troubleshooting

Who is this for: The Vintruep 6AN CPE braided fuel line is intended for automotive enthusiasts, fabricators, race teams and mechanics who need a dependable AN6 supply hose for fuel, oil, or vacuum systems. Choose this hose when you require elevated pressure capability, chemical compatibility with common automotive fluids, and a length option that supports complex routing. If you anticipate tight bends, consider planning routing or using additional fittings to preserve hose life.
