6an Male Union Stainless Steel

The EARLS 6AN Male Union Stainless Steel straight adapter (SS981506ERL) is a precision fluid line connector designed to join two 6 AN male ports in high-performance hydraulic and fuel systems. This fitting delivers direct port-to-port connection without reducing flow capacity, making it the go-to choice for race-proven fuel systems, custom hydraulic setups, and motorsport applications where clean, leak-free joints are non-negotiable.

Constructed from stainless steel, this 6 AN union fitting resists corrosion and maintains structural integrity across temperature swings common in high-output engines. The 6 AN specification denotes a -6 JIC thread size, which supports the flow volumes required in modern fuel injection and pressurized cooling circuits. EARLS stainless fittings are manufactured to tight tolerances, ensuring that each joint seats consistently and holds pressure without weeping under sustained load—a critical requirement in competitive motorsports and street performance builds where system reliability directly impacts safety.

This adapter is essential for builders who need to consolidate fuel lines, redirect hydraulic flow, or adapt between engine bay space constraints. Its compact footprint (0.85 × 0.85 × 1.4 inches) and lightweight construction (0.08 lbs) make it ideal for tight installation scenarios in engine compartments. Drag racers, road race teams, and custom fabricators rely on stainless steel union fittings to create repeatable, durable plumbing architectures that withstand vibration, thermal cycling, and peak system pressures without compromise.
