-8 90 Degree Fitting

The -8 90 Degree Fitting from VINTAGE AIR is a precision hose end connector engineered for modern air conditioning and refrigerant systems in automotive applications. This 90-degree angle fitting connects 8 AN hose crimps to 8 AN female O-ring ports, making it essential for tight-space AC routing where direct connections won't fit. Whether you're upgrading a classic car's climate control, retrofitting a custom cooling loop, or fabricating a high-performance thermal management system, this fitting solves the real-world challenge of navigating engine bays with limited clearance and unconventional layouts.

Constructed from aluminum and steel with a natural finish and zinc oxide protective coating, the -8 90 Degree Fitting delivers reliable performance under refrigerant pressure while resisting corrosion in underhood environments. The 8 AN hose crimp end accepts properly-sized crimp fittings for a leak-free seal, while the 8 AN female O-ring port accommodates matching male connectors with integral O-rings for a redundant sealing system. This dual-seal approach—crimp on one end, O-ring on the other—is standard in professional AC work and ensures durability across thermal cycling and vibration exposure. The 90-degree geometry allows hose runs to change direction without kinks or flow restriction, critical for maintaining system efficiency in compact installations.

Mechanics and fabricators building custom air conditioning systems, vintage car restorations, or engine swap projects rely on this fitting to adapt hose routes around engine block corners, firewall penetrations, and suspension geometry. The compact 5.85 x 1.15 x 7.8-inch dimensions and light 0.14-pound weight make it easy to position in tight quarters without adding bulk. Ensure proper hose size matching (8 AN throughout) and verify that both connection ends are clean and free of debris before installation. Use appropriate torque specifications for O-ring fittings and avoid over-tightening to prevent damage to the aluminum body.
