12AN to 12AN 3/4NPT Straight Male to Male

The 12AN to 12AN 3/4NPT Straight Male to Male adapter from REDHORSE PERFORMANCE is designed for high-pressure fluid systems that require secure, leak-free connections between AN-spec hose lines and NPT-threaded ports. This fitting is essential for builders and technicians working with fuel systems, hydraulic circuits, and transmission cooler lines where mixing AN and NPT standards is unavoidable.

The straight configuration of this adapter ensures direct alignment and minimal turbulence in flow paths, making it ideal for performance and racing applications where reliability and consistency are critical. It features precision-machined construction with both 12AN JIC (37-degree flare) and 3/4" NPT (National Pipe Taper) threads, allowing seamless integration between different plumbing standards without reducing flow capacity or introducing stress points.

This fitting is particularly beneficial for technicians upgrading or customizing fuel systems, transmission lines, or cooler circuits on performance vehicles and engines. Its compact footprint—measuring 2.75 x 1.4 x 3.8 inches—fits tight engine bays without requiring additional adapters, thereby reducing complexity and potential leak paths in critical systems.
