1/4in Hose to 1/8in NPT Male 90Deg Blue

The 1/4in Hose to 1/8in NPT Male 90Deg Blue adapter from REDHORSE PERFORMANCE is a precision-engineered fitting designed for high-performance fuel, oil, and fluid transfer systems. This 90-degree adapter bridges hose-barb and NPT thread connections, making it essential for custom hydraulic lines, fuel injection systems, and pressurized fluid applications where space constraints or routing requirements demand angled connections. Built to withstand demanding automotive, marine, and industrial environments, this fitting ensures leak-free operation and reliable performance in systems operating under pressure.

Constructed from aluminum and finished with blue anodized coating, this adapter combines lightweight durability with corrosion resistance and visual identification in complex fluid systems. The 1/4-inch hose barb end secures tubing with a positive mechanical grip, eliminating the need for additional clamps in most applications, while the 1/8-inch NPT male thread end connects directly to female NPT ports on components, manifolds, or block fittings. The 90-degree angle design optimizes space efficiency in tight engine bays and custom installations, reducing sharp bends in hose runs that could otherwise restrict flow or cause premature hose failure. Anodized finishes provide both aesthetic appeal and enhanced wear resistance against fluid degradation and environmental exposure.

This fitting suits fabricators, automotive enthusiasts, and performance engine builders who demand precision plumbing in fuel systems, cooling circuits, and pressurized reservoirs. Compatible with standard 1/4-inch ID tubing and any component featuring 1/8-inch NPT female ports, the adapter is ideal for carbureted and EFI fuel systems, turbo coolant lines, and custom hydraulic installations. Installation is straightforward—simply push tubing onto the barb end until fully seated and thread the NPT end into the receiving port using appropriate thread sealant for pressurized applications. Each unit ships individually, ready for immediate integration into your system.
