This product is ideal for serious automotive enthusiasts and professional mechanics who demand reliability under extreme conditions. It connects AN-specification hose to hard-line or component ports, making it essential for turbocharged engine bays and custom fuel delivery systems.

Manufactured from durable black-anodized aluminum, the 4AN PTFE Hose Ends Black 90 features a PTFE inner sealing surface that resists corrosion and maintains structural integrity across temperature swings common in aggressive motorsports environments. The 90-degree angle design allows for tight routing around engine components and frame rails without kinking the hose or compromising flow.
