#3 > 1/8 Npt Steel

The EARLS #3 to 1/8 NPT Steel straight adapter fitting (model 961603ERL) is a precision-engineered AN to NPT conversion connector designed for hydraulic and pneumatic line integration in high-performance applications. This steel adapter enables seamless connection between a #3 AN male port and a 1/8 inch NPT male threaded system, making it essential for custom fuel systems, brake lines, and air suspension configurations.

Constructed from zinc-plated steel, this adapter provides corrosion resistance critical in under-hood and exposed environments where salt spray, moisture, and temperature cycling pose oxidation risks. The straight configuration eliminates offset or angular deflection, ensuring direct flow paths and reducing turbulence at connection points. The zinc plating also facilitates visual inspection, signaling maintenance intervals before catastrophic failure.

This fitting serves builders and technicians modernizing carburetor fuel delivery systems, upgrading mechanical fuel pumps to electric systems, and fabricating custom transmission cooler circuits. The AN-to-NPT adapter bridges the gap between different connection standards, ensuring compatibility across various automotive and industrial applications.
