45 Deg Adapter Fitting #12 x 1/2 MPT Black

The 45 Deg Adapter Fitting #12 x 1/2 MPT Black from FRAGOLA is an essential component for custom fuel, coolant, and hydraulic systems in high-performance automotive builds. Whether you're fabricating a custom engine bay layout, upgrading your fuel delivery system, or routing brake lines in a race car, this 45-degree adapter allows you to change line direction without kinking or restricting flow. Designed for builders and mechanics working on modified vehicles where OEM routing won't work, this fitting solves common spatial constraints in tight engine compartments and custom installations.

Constructed from durable black-anodized aluminum, the 45 Deg Adapter Fitting #12 x 1/2 MPT combines lightweight construction with corrosion resistance—critical for long-term reliability in performance applications. The #12 designation indicates a -12 AN (5/8") hose size, while the 1/2 MPT (Male Pipe Thread) port accepts standard half-inch NPT connections, making it compatible with most aftermarket fuel rails, regulators, and distribution blocks. FRAGOLA's precision engineering ensures leak-free connections under high pressure, with a 45-degree angle that maximizes clearance and minimizes turbulence compared to 90-degree alternatives.

This adapter is ideal for turbocharged, supercharged, and naturally aspirated engine swaps where fuel system plumbing must navigate around headers, intake manifolds, and custom brackets. Engine builders, hot rod fabricators, and motorsports mechanics rely on FRAGOLA adapters to create clean, efficient fuel and coolant circuits that withstand vibration and thermal cycling. Weighing only 0.15 pounds and measuring 1.95 x 1.35 x 4 inches, the compact profile fits into confined spaces without sacrificing connection strength, making it essential for LS, EFI, and standalone ECU fuel system conversions.
