Male -6AN to Male 1/4in NPT 90 Degree Fitting

The Male -6AN to Male 1/4in NPT 90 Degree Fitting (SKU VIB11354) is an essential adapter for any serious engine bay modification or fuel system upgrade. Whether you're building a high-performance fuel system, installing an aftermarket fuel regulator, or integrating custom gauges and accessories, this 90-degree adapter bridges the gap between AN (Army-Navy) fittings and NPT (National Pipe Thread) connections. This fitting is purpose-built for those who demand reliability in critical fuel, oil, and coolant transfer applications where standard hose clamps simply won't cut it.

Constructed from black anodized aluminum, this adapter combines lightweight construction with corrosion resistance—crucial in engine compartments exposed to heat cycles, moisture, and fuel vapors. The 90-degree orientation allows flexible routing in confined spaces, eliminating the need for excessive tubing bends that weaken hose integrity and reduce flow efficiency. The male 6AN end accepts standard AN hose fittings with JIC flare seats, while the male 1/4in NPT swivel end threads directly into gauge ports, carburetors, fuel rails, or manifold bosses without requiring separate adapters. This design eliminates leak points and simplifies installation, making it ideal for custom fuel system plumbing, boost gauge installations, or oil pressure line connections in turbocharged and supercharged applications.

Mechanics and fabricators routinely specify this fitting for fuel injection conversions, custom fuel cell installations, and aftermarket carb upgrades where factory hardlines require rework. Its compact footprint (3.54 x 1 x 6.3 inches) and minimal weight (0.07 lbs) make it suitable for weight-conscious builds, while the swivel design accommodates minor misalignment without stressing adjacent components. Installation is straightforward: thread the NPT end into your manifold or gauge port with appropriate thread sealant, connect your AN hose or hard line to the 6AN end, and secure with a wrench. This adapter is compatible with any fuel system, oil system, or coolant circuit operating within standard automotive pressure and temperature ranges.
