16AN Flare Plug 1/pkg Black

The 16AN Flare Plug 1/pkg Black from REDHORSE PERFORMANCE is an essential hydraulic fitting component for any serious automotive build, fuel system upgrade, or high-pressure application where reliability is non-negotiable. This single-pack offering serves mechanics, hot rod builders, and performance enthusiasts who demand precision-engineered connections in their custom fuel lines, cooling systems, or brake circuits. Whether you're assembling a fuel injection retrofit, upgrading to braided stainless lines, or fabricating a custom fuel cell setup, a quality AN flare plug ensures leak-free, vibration-resistant connections that hold pressure under demanding conditions.

The 16AN designation refers to a -16 AN port size, which accommodates standard -16 hose and line configurations common in fuel systems and hydraulic applications rated for high-pressure operation. REDHORSE PERFORMANCE's black finish provides corrosion resistance while the flare design creates a secure, sealed connection when mated with corresponding -16 AN female ports or fittings. The compact form factor—weighing just 0.14 lbs with dimensions of 2.75 x 1.4 x 3.75 inches—allows for tight installation spaces without compromising structural integrity. This plug terminates unused 16AN ports, prevents fluid loss, and maintains system pressure integrity during testing, operation, or future reconfiguration of fuel and hydraulic circuits.

Builders working with aftermarket fuel systems, custom cooling loops, or modular engine bays will find this plug indispensable when installing -16 AN manifolds or block adapters with excess ports. Purchase a single plug for immediate use or stock multiples as spares for future projects—AN fittings are standardized across racing, street performance, and marine applications, making -16 plugs universally compatible with any system using 16AN ports. Installation is straightforward: thread the plug into the desired -16 port until hand-tight, then apply moderate torque with an appropriately sized wrench to ensure a permanent seal without over-torquing and damaging the flare seat.
