Elbow Fitting

The Holley elbow fitting is a 90-degree brass adapter designed for fuel system plumbing, coolant lines, and vacuum hose applications in custom engine builds and automotive modifications. This adapter bridges two perpendicular connection points where space or routing constraints demand a compact directional change, making it essential for engine bay layouts that require precision plumbing without kinks or long runs. Whether you're fabricating a fuel cell setup, installing a turbo cooling circuit, or routing pneumatic lines in a performance build, this fitting delivers the directional control that professional mechanics and serious enthusiasts rely on.

Constructed from durable brass with natural finish, the Holley 26-69 elbow fitting features 1/8-inch NPT (National Pipe Thread) connections on both ends—female inlet and male outlet. This configuration allows seamless integration into existing NPT-threaded systems without requiring additional adapters, and brass material resists corrosion while maintaining integrity under moderate fuel and coolant pressures typical of street and mild racing applications. The compact 3.5 x 0.65 x 5-inch profile minimizes installation footprint, critical when navigating tight engine compartments or custom intake manifold configurations.

Mechanics and engine builders favor Holley fittings for stock-replacement repairs and full system upgrades alike, from classic muscle car restorations to modern LS conversions and forced induction platforms. Installation requires only standard wrenches and thread sealant tape; the 90-degree angle eliminates the need for offset or elbow hoses that can degrade under heat cycles. Verify NPT compatibility with your fuel pump discharge, carburetor inlet, or ancillary system before purchase to ensure proper thread engagement and leak-free operation.
