#16 Str Swivel-Seal

The #16 Str Swivel-Seal is a precision hose end fitting designed for high-pressure hydraulic and fluid transfer systems in modern performance vehicles and custom builds. This fitting serves as the critical connection point between AN hose lines and female AN ports, making it essential for anyone upgrading fuel systems, coolant lines, power steering, or custom fluid management setups. Whether you're a serious enthusiast fabricating a custom engine bay or a professional mechanic executing a complete system overhaul, this swivel-seal fitting delivers the leak-free, vibration-resistant performance that separates reliable builds from problematic ones.

Constructed from aluminum and finished in blue/red anodized coating, the #16 Str Swivel-Seal features a straight configuration that accommodates 16 AN hose to 16 AN female connections without orientation restrictions. The swivel design allows the fitting to rotate freely, eliminating torque stress on hose and port threads during installation and thermal cycling—a critical advantage in engine compartments subject to extreme temperature swings. The anodized finish provides corrosion resistance and durability in both street and track environments, while the precision machining ensures zero-clearance seating and consistent pressure ratings. Weighing just 0.26 lbs, this compact fitting minimizes system weight without compromising structural integrity.

This fitting is ideal for builders working with 16 AN braided hose systems—common in LS engine swaps, fuel system upgrades, and race car builds where reliability under sustained pressure is non-negotiable. The swivel-seal design prevents hose kinking and reduces installation time compared to fixed fittings, making it particularly valuable when routing lines through tight engine bays or around complex component layouts. Installation is straightforward: ensure proper hose crimping to AN specifications, apply a thin layer of thread sealant to the male threads, and torque to the appropriate AN fitting specification. Compatible with both street and racing applications, the #16 Str Swivel-Seal is an investment in system longevity and performance.
