The #10 to 3/8 NPT Adapter (EAR981611ERL) is a straight-thread fitting designed to bridge connections between 10 AN (Air/Nitrogen) male ports and 3/8-inch NPT (National Pipe Thread) male ports. This aluminum adapter with blue anodized finish is engineered for hydraulic, pneumatic, and fluid transfer systems where SAE AN and NPT thread standards must interface. The compact design and lightweight construction make it suitable for high-pressure applications, motorsports fuel systems, air suspension setups, and industrial fluid routing where space efficiency is critical.
Aluminum construction provides corrosion resistance and reduces overall assembly weight—a key advantage in performance automotive and aerospace applications. The blue anodized finish adds a protective oxide layer that enhances durability against oxidation and wear in demanding environments. Weighing only 0.05 lbs and measuring 1.45 x 1.1 x 2.85 inches, this adapter integrates seamlessly into compact installations where clearance and weight are considerations. The straight-thread configuration ensures direct alignment without flow direction complexity, making it ideal for quick installation and maintenance.
This adapter serves technicians, fabricators, and system integrators who regularly mix SAE AN and NPT connections in custom fuel systems, turbo setups, air braking lines, and pressure gauge installations. Common applications include engine bay plumbing where space is limited, aftermarket cooling system modifications, and retrofit projects requiring compatibility between legacy NPT fittings and modern AN quick-disconnect components. The adapter's straightforward design eliminates the guesswork in matching thread standards.
AN and NPT thread systems operate on different pitch and cone angles, so direct mixing requires precision adapters. This fitting handles the translation reliably, making it an essential component for builders who source parts from different suppliers or integrate older equipment into new assemblies. Proper thread sealing compound is recommended for NPT connections to ensure leak-free performance under pressure.
