The 4AN Flare Cap Nut 2 Piece Blue from REDHORSE PERFORMANCE is an essential component for automotive fuel systems, particularly for those upgrading or customizing fuel lines. Designed for -4 AN (Army-Navy) hose fittings, these cap nuts provide a reliable seal for the flared ends of fuel lines, ensuring leak-free connections under pressure.
Constructed from anodized aluminum, the 4AN Flare Cap Nut features a two-piece design that simplifies installation and removal compared to integrated assemblies. The blue anodized finish not only enhances its aesthetic appeal but also provides a protective oxide layer against oxidation, making it suitable for use in engine bays and fuel tank compartments.
These cap nuts are ideal for professional mechanics and performance enthusiasts working on turbocharged, supercharged, or naturally aspirated builds where fuel system integrity is critical. Their hex-head design allows for proper torque application, preventing over-tightening that could damage the flared seat, making them a reliable choice for any fuel system application.
