12an to 1in MPT 90-Deg. Adapter Fitting - Black

The 12AN to 1in MPT 90-Degree Adapter Fitting in Black from FRAGOLA is an essential component for custom fuel, oil, and coolant line routing in high-performance engine builds. Whether you're assembling a turbo fuel system, upgrading your cooling circuit, or fabricating a custom hydraulic line setup, this adapter bridges the gap between -12 AN (3/4" ID) hose and 1-inch NPT threaded ports on engine blocks, radiators, and aftermarket components. Mechanics and fabricators rely on FRAGOLA's precision adapters to ensure leak-free connections under extreme pressure and temperature conditions.

This 90-degree configuration allows tight routing around engine bay obstacles, critical when space is limited in modified or engine-swapped vehicles. The black anodized aluminum construction resists corrosion and vibration degradation, while the precision-machined male pipe thread (MPT) end ensures a rock-solid fit into female NPT ports without seeping or weeping under boost or high-flow conditions. The AN hose end accommodates standard -12 AN braided hose with a reusable -12 AN fitting, eliminating the need for compression fittings and reducing potential failure points in your system.

This adapter is ideal for street rods, race cars, turbo conversions, and engine swaps where OEM coolant and fuel ports don't align with modern braided line systems. The compact 2.5-inch footprint and lightweight 0.25-pound design make installation straightforward in tight engine compartments, and the 90-degree bend eliminates sharp hose kinks that restrict flow and weaken lines over time. Thread sealant tape or PTFE paste is recommended for the MPT connection to guarantee a leak-free seal on pressurized systems.
