16an Fitting - Black Extended Length

The 16AN Fitting - Black Extended Length is a precision hydraulic adapter engineered for custom automotive fuel, coolant, and power steering applications where direct male-to-male connections are required. Mechanics and fabricators building high-performance street rods, race cars, and modified trucks rely on this fitting to create clean, compact manifold layouts and eliminate unnecessary tubing runs. The extended length design provides critical clearance in tight engine bays while maintaining full flow capacity across premium hydraulic systems.

Constructed from aluminum and finished in black anodize, this 16 AN male-to-male O-ring adapter combines lightweight construction with corrosion resistance and a professional appearance. The O-ring face seal design ensures leak-free connections under high pressure and temperature cycling—critical for applications experiencing fuel pressure spikes, coolant bypass flows, or transmission fluid circuits. Extended length geometry reduces stress concentration at connection points and allows installers to position hard lines at optimal angles without compromising fitting strength or creating dead spots in fluid delivery.

This adapter fits directly into any 16 AN ported component—carburetors, fuel pressure regulators, oil coolers, transmission coolers, and custom manifold blocks—making it ideal for builders upgrading or reconfiguring cooling systems on LS swaps, vintage engine restorations, and turbocharged platforms. Installation requires standard AN wrench sizes and compatible 16 AN hard line or hose. Each fitting ships individually, allowing you to order exactly the quantity needed for your specific plumbing configuration without waste.
