#6 In Line Service Port

The #6 In Line Service Port by Vintage Air is a precision refrigerant fitting designed for professional and enthusiast-level automotive air conditioning system work. This straight hose-end adapter serves as a dedicated charge port, allowing technicians to safely connect diagnostic equipment and refrigerant recovery tools to AC systems during maintenance, evacuation, or recharge procedures. Whether you're performing seasonal AC service on classic muscle cars, modern performance builds, or restoring vintage climate control systems, this fitting provides a reliable interface between your hoses and the vehicle's refrigerant circuit.

Engineered with a straight configuration and featuring 6 AN hose crimp connections on both ends, the #6 In Line Service Port accommodates standard -6 refrigerant hose without adapters or reducers. The fitting is constructed from a combination of aluminum and steel components with natural and zinc oxide finishes, ensuring corrosion resistance during repeated service cycles and exposure to moisture-rich workshop environments. The crimp-style connections deliver a leak-free seal critical to AC system integrity, preventing refrigerant loss and maintaining proper system pressure during diagnostics and charging operations.

This service port is essential for shops and DIY builders maintaining R-134a or compatible refrigerant systems on street rods, hot rods, and retrofit air conditioning installations. The compact 4 x 1 x 6.4 inch profile fits tight engine compartment configurations typical of custom builds, while the straightforward design integrates seamlessly into existing AC lines. Professional technicians rely on Vintage Air fittings for their durability and dimensional accuracy; the #6 specification ensures compatibility with standard -6 AN hose crimps used throughout aftermarket climate control kits and OEM-style systems.
