HS-79 90-Deg Hose End 16 Hose to 12an Nut

The HS-79 90-Deg Hose End 16 Hose to 12an Nut is a precision-engineered fuel line and cooling system component built for serious automotive builders and performance mechanics. This XRP-Xtreme Racing Products adapter is purpose-built for custom engine builds, supercharger installations, and high-flow fuel delivery systems where reliable, leak-free connections are non-negotiable. Whether you're upgrading a street machine with modern fuel injection or plumbing a competition engine bay, this 90-degree hose end delivers the directional control and ANT (Army-Navy Thread) compatibility your system demands.

The HS-79 features a 90-degree elbow configuration that solves tight routing challenges where straight hose ends create clearance conflicts or require excessive bends in the hose itself. The 16-size hose barb accepts standard braided stainless steel or silicone hose, while the 12an (AN12) nut threads onto -12 AN bulkhead fittings, fuel rails, and block adapters with precision. XRP's hose ends are manufactured to exacting tolerances, ensuring a secure crimp that resists vibration-induced loosening and withstands pressure spikes common in forced induction and carbureted high-flow applications. The anodized aluminum construction balances weight savings with corrosion resistance, critical for underhood longevity in both street and track environments.

This adapter is ideal for engine builders transitioning vintage carburetor systems to EFI, installing aftermarket fuel pumps with remote filters, or managing complex coolant bypass loops in turbocharged and supercharged platforms. Mechanics working on LS swaps, small-block conversions, and modern engine transplants regularly specify XRP hose ends to eliminate leak points and achieve the clean plumbing lines professional builds demand. Proper installation requires a hose crimper that matches your hose barb size; ensure you use stainless or braided hose rated for your system pressure to guarantee reliability under boost or high fuel flow conditions. Compatible with any -12 AN threaded port on fuel systems, cooling circuits, and hydraulic lines.
