Straight Adapter Fitting #6 x 1/4 MPT

The Straight Adapter Fitting #6 x 1/4 MPT by FRAGOLA is a precision hydraulic and fuel system connector engineered for applications requiring a seamless transition between 6 AN male ports and 1/4 inch NPT male threads. This adapter serves technicians, fabricators, and motorsports enthusiasts who need reliable, leak-free connections in high-pressure fuel systems, brake lines, and custom hydraulic setups. The straight configuration ensures direct alignment without offset, making it ideal for tight engine bays and compact plumbing scenarios where space efficiency is critical.

Machined from aerospace-grade aluminum and finished in vibrant blue anodizing, the 481606 adapter combines durability with corrosion resistance in demanding environments. The blue anodized coating not only protects against oxidation and salt spray but also provides visual identification for quick system diagnostics. The aluminum construction keeps weight minimal—just 0.02 lbs—while maintaining the structural integrity required for sustained pressure cycling. The 6 AN male thread accepts industry-standard -6 hose fittings, while the 1/4 inch NPT male end threads directly into female NPT ports found on carburetors, fuel pressure regulators, and manifold blocks.

Professional mechanics, drag racers, and street machine builders rely on FRAGOLA adapters for fuel system modifications, turbo installations, and auxiliary fuel pump setups where NPT threaded ports are standard. Installation is straightforward: apply appropriate thread sealant to the NPT end and hand-tighten into the target port, then secure the -6 hose connection with a suitable AN hose clamp. Compact dimensions (1.1 x 0.85 x 4.25 inches) allow placement in confined areas without compromising system flow or pressure ratings suitable for carbureted and EFI fuel delivery systems alike.
