1/4 NPT 90-Deg Fitting Male/Female - Black

The 1/4 NPT 90-Deg Fitting Male/Female in Black is a precision hydraulic and pneumatic adapter engineered for custom fuel, oil, coolant, and air brake line routing in performance vehicles and modified engines. Whether you're building a custom fuel system, installing a turbocharger intercooler setup, or routing remote filtration and cooler lines, this elbow fitting provides the reliable directional change needed to navigate tight engine bays and unconventional layouts. It's an essential component for fabricators, engine builders, and enthusiasts tackling serious vehicle modifications where standard routing won't work.

Machined from durable black-anodized aluminum alloy, this 90-degree fitting features NPT (National Pipe Thread) male and female ports, ensuring leak-free connections when properly sealed with thread tape or paste. The 1/4-inch NPT size strikes a balance between flow capacity and compact installation footprint—ideal for secondary circuits, gauge feeds, and auxiliary system plumbing where excessive diameter would complicate routing. The 90-degree geometry allows you to change line direction without adding multiple components or excessive hose runs, reducing complexity and potential leak points in high-vibration engine compartments.

This fitting is compatible with fuel injection tuning systems, oil cooler setups, intercooler piping, power steering upgrades, and vacuum distribution networks common in LS swaps, turbo conversions, and supercharger installations. The lightweight construction (0.05 lbs) makes it ideal for weight-conscious builds, and the black finish resists corrosion in underhood environments. Installation is straightforward—thread male ports into female ports on manifolds, blocks, or hose adapters, torque to manufacturer specs, and seal with appropriate thread sealant for your fluid type. FRAGOLA fittings are trusted throughout the automotive performance community for consistent quality and reliable pressure ratings.
