#8an to #6an Steel Union Reducer Fitting

The AEROQUIP #8AN to #6AN Steel Union Reducer Fitting (FCM2758) is a precision hydraulic adapter designed for modifications in fuel, oil, and coolant systems, particularly in high-performance vehicles. This reducer fitting is essential for creating junctions in custom fuel systems, turbo oil lines, and transmission coolers where line diameter transitions are necessary.

Constructed from durable steel, this union reducer features male threads on both ends to accommodate hose barbs or swaged fittings at each diameter. The #8AN connection allows for larger-diameter hose assemblies, while the #6AN outlet reduces flow to smaller-gauge lines. This design is critical for applications requiring effective pressure management and line consolidation.

Professional builders working on fuel injection systems, turbocharger feed lines, and auxiliary cooling loops will find this fitting particularly beneficial. Its compact design (2.25 x 1.1 x 3.7 inches) integrates seamlessly into tight engine bays without compromising structural strength or sealing capability.
