1/8 x 1/2 Pipe Reducer Bushing

The 1/8 x 1/2 Pipe Reducer Bushing by FRAGOLA is a precision adapter fitting designed for hydraulic systems, fuel lines, and pneumatic applications where port size reduction is essential. This NPT (National Pipe Thread) bushing allows technicians and fabricators to connect larger 1/2-inch male ports to smaller 1/8-inch female inlets, making it indispensable for custom fuel system builds, brake line configurations, and engine bay plumbing modifications. Whether you're downsizing flow paths in a performance fuel system or adapting legacy components to modern specifications, this reducer bushing eliminates the need for multiple fittings or costly custom machining.

Manufactured from aluminum and finished in blue anodizing, this fitting combines lightweight construction with excellent corrosion resistance—critical for underhood environments exposed to fuel, oil mist, and temperature cycling. The blue anodized coating not only protects the aluminum from oxidation but also serves as a visual identifier in color-coded system builds, helping technicians quickly verify correct connections during installation and troubleshooting. The tapered NPT threads create a positive seal without requiring thread sealant tape in most applications, though PTFE tape is recommended for maximum reliability on high-pressure or vibration-prone systems found in racing and off-road vehicles.

Professional mechanics, fabricators, and enthusiasts building or modifying fuel injection systems, turbo feed lines, and intake charge cooling systems will find this reducer bushing essential for compact manifold work and tight engine bay layouts. Its compact footprint—measuring 3.9 x 1 x 5.55 inches—fits easily into congested areas without adding bulk or weight. Compatible with any NPT-threaded component, this fitting works seamlessly in both steel and aluminum systems, making it a universal solution for carburetor conversions, E85 fuel system upgrades, and custom cooling circuit installations where port adaptation is required.
