1/4in Hose to 1/8in NPT Male 45Deg Blue

The 1/4in Hose to 1/8in NPT Male 45Deg Blue adapter from REDHORSE PERFORMANCE is a precision fluid transfer fitting designed for hydraulic, pneumatic, and fuel system applications where space constraints or tight angles require an angled connection. This 45-degree adapter bridges two different port sizes—a 1/4-inch hose barb inlet and a 1/8-inch NPT male threaded outlet—making it essential for custom plumbing in race vehicles, industrial equipment, and performance automotive builds. The angled design eliminates the need for rigid tubing elbows, reducing weight and improving serviceability in cramped engine bays or equipment housings.

Machined from aluminum and finished in blue anodized coating, this fitting offers corrosion resistance and a professional appearance while maintaining lightweight construction—critical in racing and aerospace applications. The hose barb design ensures a secure, interference-fit connection that requires no additional clamps for low-pressure applications, though hose clamps are recommended for high-pressure or vibration-intensive environments. The 45-degree orientation allows installers to route hose runs cleanly around obstructions and engine components while maintaining proper flow dynamics and reducing stress on the hose at the connection point.

This adapter benefits drag racers, circle-track competitors, and custom fabricators who demand precision fittings that minimize installation time and component count. It pairs with 1/4-inch diameter hose and NPT-threaded female ports or manifolds commonly found in fuel systems, coolant circuits, and air suspension components. The compact 2.85 x 1.15 x 3.85-inch footprint makes it ideal for tight installations where traditional 90-degree elbows or bulky adapters cannot fit, ensuring reliable performance across temperature and pressure ranges typical in motorsports and industrial duty.
