1/4in Hose to 1/8in NPT Male Straight Blue

The 1/4in Hose to 1/8in NPT Male Straight Blue fitting by REDHORSE PERFORMANCE is a precision adapter designed for hydraulic and pneumatic systems in custom automotive applications. This compact connector bridges two different port sizes—1/4-inch hose barb inlet to 1/8-inch NPT male outlet—making it essential for fuel injection tuning, air suspension builds, intercooler plumbing, and brake system modifications. Whether you're fabricating a custom fuel rail, integrating auxiliary cooling lines, or routing pressurized air systems in a performance vehicle, this straight fitting delivers the reliable connection point your build demands.

Engineered by REDHORSE PERFORMANCE, a trusted name in automotive plumbing solutions, this fitting features a straight design that minimizes turbulence and pressure drop across the connection. The blue anodized aluminum body provides corrosion resistance and durability in high-vibration engine compartments, while the NPT male thread (National Pipe Taper) ensures leak-free sealing when wrapped with proper PTFE tape or pipe dope. The 1/4-inch hose barb secures push-on tubing with a tight mechanical grip, eliminating the need for crimped ferrules in many applications. At just 0.04 lbs and measuring 2.75 x 1.15 x 3.8 inches, the fitting maintains a low-profile footprint ideal for tight engine bay layouts.

This adapter suits amateur fabricators, professional tuners, and mechanics upgrading fuel delivery, cooling, or air management systems on street rods, turbocharged engines, and off-road platforms. The straight configuration works where 90-degree or 45-degree elbows would create packaging conflicts or restrict flow rate. Installation requires only standard hose clamps on the 1/4-inch barb side and a wrench on the NPT outlet for block-mounted components. Buy this fitting as a replacement component or stock it for modular build work; its compact design makes it a reliable addition to any serious automotive modification shop's plumbing inventory.
