The EARLS St. #6 to 1/2 NPT Adapter (part number 981668ERL) is a straight-thread fitting designed to connect 6 AN male ports to 1/2 inch NPT male connections. This aluminum adapter features blue anodized coating for corrosion resistance and is engineered for high-pressure hydraulic and pneumatic systems commonly found in performance engines, fuel systems, and custom fabrication work. The compact 1/2 NPT male end accepts standard pipe thread components while the 6 AN male side integrates seamlessly into modern AN-threaded plumbing networks.
The straight configuration eliminates directional complexity during installation and routing. Aluminum construction keeps overall weight minimal—a critical factor in race and motorsport applications where every ounce affects performance. Blue anodizing provides reliable protection in high-temperature engine bays and protects against fluid contamination that can compromise system integrity. The 6 AN to 1/2 NPT thread match is a standard industry pairing, making this adapter essential for connecting legacy NPT-threaded components (gauges, sensors, valves) to modern AN-plumbed fuel rails, coolant circuits, and boost systems.
This adapter addresses the practical challenge of mixing thread standards in custom engine builds, trailer systems, and industrial applications. Whether transitioning from older NPT-based fuel delivery to modern AN standards or integrating aftermarket gauges into a contemporary plumbing layout, this EARLS fitting ensures reliable, leak-free connections under load. Professionals in automotive fabrication, marine propulsion, and off-road suspension systems regularly stock this adapter size for quick system modifications and component upgrades.
The EARLS brand is recognized throughout the performance and motorsport industries for precision hose and fitting engineering. This single adapter unit is sold individually, allowing you to purchase exactly the quantity needed for your specific plumbing configuration without waste or excess inventory.
