1/8 NPT to 1/4 Barb Stra ight Fitting

The 1/8 NPT to 1/4 Barb Straight Fitting from VIBRANT PERFORMANCE is a precision adapter designed for fluid transfer systems where reliable connections between different hose and port sizes are critical. This fitting bridges a 1/8 inch NPT male thread to a 1/4 inch barbed outlet, making it essential for coolant lines, fuel systems, vacuum tubing, and pneumatic applications in automotive, motorsports, and industrial environments. The straight configuration ensures minimal turbulence and optimal flow without directional restriction, ideal for applications requiring consistent pressure and leak-free performance.

Constructed from aluminum and finished in black anodized coating, this fitting combines lightweight durability with superior corrosion resistance and aesthetic consistency across modern engine bay setups. The black anodized surface protects against oxidation while maintaining a professional appearance in visible installations. The barbed end is engineered to accept hose securely without requiring additional clamps in low-pressure applications, though industry best practice recommends hose clamps for enhanced security. VIBRANT PERFORMANCE's precision manufacturing ensures tight tolerances on both the 1/8 NPT thread and 1/4 inch barb, eliminating common leak points at connection interfaces.

This adapter serves users upgrading or customizing cooling systems, fuel delivery setups, and pneumatic control lines where OEM fittings don't align with aftermarket component thread sizes. It works seamlessly with 1/4 inch ID hose and pairs effectively with any NPT-threaded port or component outlet. Installation is straightforward: thread the NPT end by hand first, then use a wrench for final tightening to prevent cross-threading. The compact 3.2 x 0.65 x 3.6 inch dimensions and minimal 0.05 lb weight make it suitable for confined engine compartments and custom fabrication projects.
