45 Male Elbow #8 To 1/2 Npt Steel Fitting

The 45 Male Elbow #8 To 1/2 NPT Steel Fitting is a precision hydraulic and pneumatic adapter designed for custom engine builds, high-performance fuel systems, and turbo plumbing applications where space constraints demand compact routing. Whether you're fabricating a custom fuel line system, integrating an aftermarket turbocharger, or building a high-pressure air suspension setup, this 45-degree elbow coupling allows you to change line direction while maintaining pressure integrity and system efficiency in tight engine bays.

Manufactured by AEROQUIP, a trusted leader in fluid power connectors, this fitting combines a male 8 AN (AN8) port with a 1/2 inch NPT male thread in durable zinc oxide–coated steel construction. The 45-degree angle geometry reduces stress concentration at bends compared to 90-degree elbows, lowering fatigue failure risk in high-vibration engine environments. The zinc oxide plating provides corrosion resistance while maintaining durability under repeated thermal cycling—critical for boost lines, coolant bypass circuits, and fuel rail applications where temperature swings are extreme.

Mechanics and fabricators favor this adapter for turbo intercooler plumbing, custom fuel cell setups, and industrial pneumatic assemblies where AN and NPT port standards must interface. The compact footprint—measuring 2.3 by 1.15 by 3.75 inches and weighing only 0.19 lbs—fits tight engine compartments without requiring bulky elbows or extra adapters. When ordering hose assemblies or building modular fuel and boost systems, verify all thread seals (PTFE tape on NPT, proper crush washers on AN fittings) to prevent leaks under pressure.
